Technology and innovation Technology helps gold rush team compete The conveyors have to efficiently transport up to 300tph of raw material for 12 hours per day at 2–2.3mps. Gold Rush, a popular television series on the Discovery channel, follows the exploits of three competing mining teams, led by Todd Hoffman, Parker Schnabel, and Tony Beets, as they seek to extract the most placer gold from their operations. While their operations may be small by commercial mining standards, the competition is fierce. The teams compete for 100 ounces of gold, which gets awarded to the team that mines most of the highly prized mineral. All three teams try to squeeze the last ounce from their operations. Therefore, the conveyors play a key role. The conveyors have to efficiently transport up to 300 tons per hour (tph) of raw material for 12 hours per day at 2–2.3 metres per second (mps). Processing begins when dump trucks empty their loads into a hopper. Rocks larger than 6″ are scalped off, and the remaining load gets screened to separate the fines from the bulk. Fines are then run through a sluice box to wash out the gold particles. “In a highly competitive situation like this, we have to collect every fraction of an ounce from the source material,” commented Trey Poulson. “Our goal this season is 5 000 ounces, and we can’t afford to leave anything behind. So even a small amount of carryback or spillage from the conveyors is a serious issue for ̸%ѡ͔Ʌѥ̰ݔeЁٔ)ɄݕȰͼ䁑ݹѥ)ȁѕȁɕ́)ͅѕȁȁ̸]eЁɐ)lt5%9%95%II=H5d)Ѽѽɽٕͥ͡)ȁɕ́ɥ)ѡȵȁݥ܁ѡЁݗeɔ)ɵѕѼɅє今t)Aձͽ́́ͅѼɅ)չȁٕ)ɑ́ѕɥɽ͕ݡ)́ЁȁՍ́յ)Ѽѡȸ]ѡѕ)ЁхѕѡɅѥѡݕɔ)ͥѡѥЁ͍Ʌ́)ѡٕ́Ѽ䁙)ѡЁɕѡ́Ёѡ)͍ɝ̸qQɥ)́ݕɕeЁ́ѥٔ́ݔ)ѡѼtͅAձͽ+qQݕɔ٥ͽ剅)ѡаݔٕ)ѡٕȁ)ѡ̸ٕ=ЁՅ)ɥѡлt)Qӊéݡѥ)ЁɅ͡܁ٔAձͽѡ)չѼЁɕɕ͕хѥٕ)ɽ5ѥɥѡ)مѽ́ɕȁ́)́Ѽձѕɥ)ȰͅȰɔ)ɽՍѥٔ!ѽѡ)éᡥЁЁѡٕЁ)хѕٕͅѥЁͽ)ѡɽ́ѡݕɔɥ)Qɕ́ݕɔЁѡ)5ѥ́ձɕͽٔ)ѡՕ́ѡ!)ѕ́ՕЁѼɽՍѡ)ѥѥAձͽ䁅ѕ)ѡéȁѼ)5ݥѠ䁉)̸+q Ё݅́)Ёх́Ёѡѥt)ɕq]ݕɔ݅ѥѠ)ѕɥȰݔձe)ɐѼٔѡЁمхѼѡ)ѥѥt)5ѥɥѕ)ɅٕѼѡ Ʌͥє)ɕ٥ݕѡѥɔٕ)ݽɬɕ)ȁͥ́ȁѥ)=ѡɕѡ)éѕѕ MɅ)ͥݡ́ɕѼ)ɽ٥́Ս́ȁѥ́ѡ)ٕѥ́)ձЁѥ̸q]$)ЁݥѠѡ5ѥ̰$)ɽՉ٥ͥ܁Ёݽձ)ݽɬ%Ё́չѡ$ٔ)͕啅́ )Ё͕́٥ȁͥѡ)ݥѡЁ́٥ѼѽՍи)ѡəɵ́ɕлt)ȁѡݕЁٕȰѡ5ѥ)ѕ͕́ѕ䵑)ɥ䁉ЁȁѡЁɕ)չՔѕѼх)ѡЁЁ)ѡɽ՝Ё͕́٥Յ)хЁٕѡѥɅ)ѡѥѥѡɕ)ѽɕЁɽ́ѡ)əɵͅ䁉䁽)ͽ́ѡٔѕ̸)ȁѡ͕䁍Ȱ՝)ͥݥѠ٥Յ䁍͡)չѕɉ́݅)хѼݥѡхѡչ͡)ѥ̸+qQ͔ٕ́ɥ)ѡ́ͅ)ͥٔɅє̳tͅMѕٔ)5-ѕɥѽ䁵ȁ
