[QUOTE="CreviceSucker, post: 517170, member: 1804"] Mine was a 4 mm rubber membrane , the leaching pad was roadbase leveled by Grader on a few degrees incline then compacted with smoothdrum rollers , the membrane covered the entire pad and the collector channel that ran around the outside diverted it onto a sump fitted with two pumps with nylon or teflon pump impellor and housing , it was pumped to other settlement ponds that had bird scaring devices around them to 'stop the birds stealing any precious metals' The leach heap was piled up about 10 metres high and they just put irrigation sprinklers on top every 6 metres to keep the stuff soaked down. The electrolysis was a sight to see , 50,000 amps of power was put across electrodes to collect the copper in sheets of 1000 mm x 1000 mm x 5 mm thick I think the acid fumes stuffed up any vehicles in the place and it probably burnt everyones nostrils worse than a coke addict but ~ it was a job...
