The Mineworx formula, made of food-grade, organic ingredients, was recently tested on e-scrap samples. HM X-leach accumulated 2,600 parts per millions of gold in the solution in less than an hour of soaking. It matches cyanides recovery rate of 97 percent over the course of about four hours.

Cyanide recovery has a significant impact on the economics of processing high cyanide-consuming copper-gold orebodies since less cyanide is required overall in the plant. When cyanide is destroyed in a gold recovery operation, the costs and hazards associated with the purchase, delivery and destruction of the reagent represents a substantial ...

2016-3-27Treatment of Cyanide Heap Leaches and Tailings 3 After leaching has been completed, such that no further recovery of gold will occur, the spent ore and remaining cyanide solution become wastes. There are several approaches to the decommissioning of cyanide-contaminated ore heaps and neutralizing of cyanide solutions.

2013-1-3Carbonaceous gold ores can have the carbon adsorb the gold onto its surface, and as a result will not be recovered from the pregnant solution. Leaching gold from sulfide ores is difficult, at best. Generally, the recovery for cyanide leaching of sulfide or refractory ores is no better than 30, which is not a worthwhile venture.

In Australia, there is also the reporting requirement of the National Pollution Inventory NPI, whereby all cyanide used in the gold recovery process must be accounted for. Thus, there is a need to clearly understand the cyanide deportment in gold processing operations, particularly in Australia.
