Solution for precipitating gold from HAuCl4

2022-02-04 · I then tried oxalic acid to drop with, then same cleaning process. I can take criticism just please be kind. I tried last week after my precipitant dropped good color nice yellow powder. I used lye to boil trying to clean out anything left. I am still getting the same drop when heated. And the same platinum, nickel, silver color result when

Management of Copper Heap Leach Projects: A Geologist's

Ores presently amenable to copper heap leaching include copper oxides and secondary copper sulfides. Most copper deposits amenable to acid sulfate heap leaching result from supergene processes within porphyry copper systems, although copper heap leaching has been applied to sandstone and shale-hosted deposits, among others.

kolkata copper ore leaching by sulphuric acid

What ores of pure metal use sulfuric acid in the process Apr 24 2022 · To start ore of pure metal is a bit contradictory Ore as a term implies that the substance is a metal containing compound which is why ores need to be either thermally or chemically or both processed in order to extract the metal For examp

The Extraction of Copper

 · Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution. Concentration of the copper(II) sulfate solution by solvent extraction. The
