Steve Smith has now scored 500-plus runs for the 2nd successive time in an Ashes series in England. The World No. 1 Test batsman is going on a batting marathon and breaking records at will to frustrate England.Steve Smith was expected to be a bit ratlled in the ongoing Test in Manchester after missing the 3rd Test in Leeds with a delayed concussion. He was hit by a vicious bouncer from Jofra Archer, bringing back memories of the fatal blow to Philip Hughes. Smith missed the 2nd innings in Lord’s. He was ruled out for the 3rd Test.England vs Australia, Ashes 2019 4th Test: Day 2 Live cricket scoreHowever, it was business as usual for the Steve Smith as he went on to notch up his 26th Test hundred on Day of the ongoging 4th Test in Manchester. Smith was spotless as he dominated the England bowlers with his unorthodox approach and tamed Jofra Archer, who was expected to trouble Smith after the Lord’s blow.However, Steve Smith presented a rare opportunity in the 75th over of the Australian innings on Thursday when he tried to drive a beautifully flighted delivery from left-arm spinner Jack Leach. Smith was batting on 118 when he was caught at first slip by Ben Stokes.Stokes’ reaction said it all. The England all-rounder, who played a heroic knock in Leeds, slammed the ball into the ground and there was more relief than delight to the England camp after they finally saw Steve Smith walking back to the pavillion.advertisementOld Trafford erupted in joy and there were even some boos from the crowd for Steve Smith, who has been in imperious form on his return to Test cricket after the ball-tampering ban.However, replays showed Jack Leach had overstepped and no part of his foot was behind the crease. Smith was called back, much to the shock of the Manchester crowd and the England players who were left distraught after the replays.England captain Joe Root took his team aside and came up with some strong words after Jack Leach’s no-ball handed the world’s best batsman an extra life.Nasser Hussain, who was doing the commentary duties, was disappointed as well. “All for nothing,” the former England said after Smith was called back.Cricket fraternity reacted to the drama at Old Trafford with quite a few witty tweets, taking digs at England cricket team.England can’t get Steve Smith out even when he walks off the pitch thinking he’s out #AshesSachin Nakrani (@SachinNakrani) September 5, 2019You know what to do Steve Smith. #Ashes pic.twitter.com/n9Nuql5pbAMikey Nicholson (@Mikey_Nicholson) September 5, 2019?? That feeling when Steve Smith is out off a no-ball… pic.twitter.com/lTvoF1npWrHawksbee & Jacobs (@tSHandJ) September 5, 2019Steve Smith. This is next level. When he’s out – he just finds a way to be not out. Genius! #AshesNed Zelic (@NedZelic) September 5, 2019Strong captaincy from Root with the bold “stop bowling no balls to Steve Smith” tactic. #AshesAdam Liaw (@adamliaw) September 5, 2019That’s what happens when Jack leach doesn’t wear his Glasses !!!!! #Ashes Michael Vaughan (@MichaelVaughan) September 5, 2019Quiet smile as I land at my desk and a no-ball and overturned wicket quiets the Steve Smith boos of boorish England fans… And with that off goes the cricket…Shawn Donnan (@sdonnan) September 5, 2019Is it possible to prorogue Steve Smith? #AshesStuart Bowman (@stuartbowman) September 5, 2019Not many bigger crimes in cricket than bowling a spinner as a no-ball. Except for getting Steve Smith out, on a no-ball, as a spinner. That’s definitely bigger. #AshesScott Bailey (@ScottBaileyAAP) September 5, 2019Oh my goodness!! That is brilliant for Steve Smith and the Aussies! Can’t wait for another 118 from him now #Ashes2019TomRehn9 (@tomrehn9) September 5, 2019England wasting so many chances. Steve Smith doesn’t need that many, he barely needs one. #AshesDominic Booth (@DomBooth19) September 5, 2019Steve Smith initially given out, but then it’s a no ball. #TheAshes pic.twitter.com/kHELhI2dW6Sheldan Keay (@SheldanKeay) September 5, 2019Steve Smith is now controlling the bowler’s feet.Jarrod Kimber (@ajarrodkimber) September 5, 2019Joe Root when England last got Steve Smith out. #Ashes pic.twitter.com/dmSp7AG6gLbetway (@betway) September 5, 2019Also See:
DRDGOLD has temporarily suspended its recently constructed high grade section – a flotation circuit, a set of fine-grind mills and the cyanide leach and CIP circuit – to determine the cause of metallurgical problems that have led to lower than expected gold production for Q3 FY14. Although the new FFG technology, introduced to liberate more gold and increase recoveries by between 16 and 20%, has achieved positive float and grinding results, the CIP section has not yet stabilised and appears to have also contributed to metallurgical instability and carbon inefficiencies downstream in the existing CIL circuit or low grade section.Suspending the new section will enable the operational team to stabilise the low grade circuit and to determine the factors that could be affecting carbon efficiencies in both circuits. The company expects the original lower-grade CIL circuit to be settled within a month. The subsequent test work is likely to be completed within a further three- to four-month period.Incessant rains in this part of South Africa during February and March and surges, dips and interruptions in the power supply during this period have also negatively impacted both the high grade and low grade sections, contributing to the metallurgical instability of both sections.The Ergo team will therefore make use of the down-time to install drain valves to prevent silting up of the float cells during future power fluctuations, and auxiliary power units to thickener underflow pumps to prevent silting up of thickeners during these trip-outs.The FFG and high grade CIP circuit came into full operation in mid-January 2014 following the commissioning of a third thickener. Initial results were positive and utilisation was generally good. Flotation efficiencies and the performance of the fine-grind mills were consistent with targets. Sampling results show that the amount of gold remaining in solids (the so-called “washed residue grade”) reduced to within target range. This suggested the gold that previously remained inert within the pyrites was now driven off and had become soluble. However, loaded carbon values remained well below the target range in both the CIP and CIL circuits. This indicated that the gold remained in solution and was not being adsorbed onto carbon. To some extent this may be attributable to poor carbon efficiency – caused by volatile density levels in the feed at various stages in the process – which in turn is attributed to the thickeners that manage the flow of feed into the main CIL section. It may also be a knock-on effect of the reagents used in the flotation cells.Currently both carbon circuits of the plant – the higher grade CIP and the lower grade CIL – are unstable and are operating well below target range.As a result of these metallurgical inefficiencies and the resultant high dissolved gold losses, gold production for the quarter ended March 2014 is estimated to be 14% lower compared to the preceding quarter, and all-in sustaining unit costs are estimated to be up by 24% quarter on quarter.In a basic summary of the FFG process and its interaction with the low grade CIL circuit, slurry is sourced from various reclamation sites and is delivered to Ergo’s Brakpan plant. The slurry, or feed, is pumped through three banks of flotation cells to create a concentrate that contains gold-bearing pyrites. The concentrate enters a set of fine-grind mills to break down the pyrites and release gold which would otherwise have remained shielded from the subsequent metallurgical extraction process. Gold trapped in these pyrites is the main target of the FFG and the reason for its construction. This fine pulp then enters a high grade leach circuit, where cyanide is added to dissolve the gold in the pulp. The concentrate is then pumped to the CIP section where activated carbon is added and the dissolved gold is adsorbed. This loaded carbon is processed through an elution circuit, where the gold is stripped off the carbon into solution. This solution then flows through a series of EW cells where the gold is electrically deposited onto electrodes. Periodically the gold is washed off the electrodes, calcined and smelted into doré bars.The remaining 96% of the feed leaves the flotation circuit and enters the low grade circuit. It first enters a set of three thickeners to increase its density before being pumped into the main CIL tanks. It is essential that the thickeners are in good working order and stable, because the high grade tail cannot be processed by the low grade circuit until it has been thickened. Their purpose is therefore to increase the density of the feed, otherwise the carbon that is introduced later in the process will sink to the bottom of the CIL tanks, and not remain in suspension. From this point onwards in the low grade CIL circuit, the feed is subjected to a similar process to the one described above – cyanidation, carbon loading, elution, electro-wining and finally smelting into doré bars.
MOST PEOPLE HAVE come across this confusing quirk of YouTube.You’ve come across some viral video, be it a surfboarding seal or a dog having a meltdown over its own reflection in a mirror. After opening it up, you glance below the video to see just how viral it has gone – but the views are only a rather vague “301+”.If you go back to the video in a few hours or the next day, the views would have suddenly jumped considerably, revealing that thousands of people watched the video.Numberphile addressed the issue, and managed to find a Youtube analytics guru, Ted Hamilton, to explain it.301+ appears when the video accumulates enough views to merit YouTube taking a closer look to ensure that they’re all real.Closer lookWhile the video can still be viewed, and views recorded, they will not appear until YouTube analyse who was watched the video using a statistical verification process.This is to ensure the views haven’t been manipulated – for example, by using bots.Ted Hamilton said that Youtube sees views as a currency.“So, a significant effort must be made to eliminate counterfeit views,” he explained.Hamilton noted that when a video has a misleading preview or title, and the analytics show a lot of people clicking in only to immediately stop watching, some of these might not be added to the final total.Any other suspect views will be disregarded.But why does it stop at 301? And not 300, or 209?Turns out this is simply an idiosyncrasy dating back to the early days of YouTube. When the code was written to dictate when the views should be analysed in more detail, a less than or equal to sign was used, instead of less than. This means that the views must reach over 300 for the effect to kick in.Confused?
