However, a close examination of the table that shows the changes in elemental compositions in the concentrate indicates that other elements are also leached into solution. This is also the case with the IGoli process developed by Mintek. They have a paper that shows how to precipitate most of the heavy metals from solution.

Maximum gold recovery at a very minimal cost in a much safer way is the prime goal of any gold processing operation. Intensive cyanidation on gravity recoverable gold is the best for maximum recovery (cost on reagents), yet, it produces a pregnant solution which must go through electrowinning (cost), and finally through smelting (another cost).

It consists of leaching the gold concentrate with dilute hydrochloric acid and bleach.
Hi guys. I found this online. Apparently these people are using a one step leach process to produce gold of high purity in large batches. Notice that they are not using DBC as the extractant, but another cheaper solvent. Anyone knows what they use?. Maybe we can dissect this process for the...
1. A method for recovering gold from carbon fines in a resin-in-leach process wherein the fines are contacted with an ion exchange resin in the presence of a suitable lixiviant whereby gold is loaded onto the resin, and the gold-loaded resin is then eluted, using a suitable eluent, whereafter gold is recovered from a resulting eluate.
