Sep 15, 2016 The most reliable way to conduct a leaching experiment is to use a vertical piece of iron pipe the depth of the tank proposed to be used in the plant, say, 6 ft. high, fitted at the bottom with a sleeve and plug, on top of which is laid a filtering medium. …
This design problem caused solids to build up around the walls and bottom of the leach tank, reducing the effective size of the tank and lowering the actual leaching time for the active slurry. This reduction in leach time ultimately resulted in lower gold recovery. To get more agitation…
Multistage agitation leaching followed by elaborate solids-liquid separation is required to recover most of the gold (up to approximately 95%) in solution, in a reasonably short time (see Chapter 4). Large tonnage of a relatively high-gold-content ore is a prerequisite for the substantial capital and operating costs required for milling.
preparation prior to leaching. Gold and silver are dissolved by cyanide in solutions of high pH in the presence of oxygen.
