Sulphide Gold Recovery. Pre-concentration of coarse 350 – 500 micron sulphide-associated gold ore, using the InLine Pressure Jig, is required to reject gangue from the high value material. The IPJ, a classic pre-concentration device, is effective in gangue rejection prior to further processing of valuable gold-bearing material.

Sulphate is a common by-product found in mine impacted water that is increasingly on the regulatory radar as a contaminant of concern. Unlike metal contaminants such as copper that are often present in mining wastewater at low levels from 0.1 to 10 mg/L, sulphate concentrations tend to be much higher and can range upwards of [.]
information on pyrtiric gold, leach . Recovery of Gold in Pyritic Sulfide Ores The now extinct Us Bureau of Mines conducted numerous studies of gold in pyrite, and sulfide ores over the years, until their untimely demise in the 1990's.
Gold and silver contained inside some sulfides amalgamates poorly, and in those early days, amalgamation was the chief recovery method for hard rock ores. The old timers developed the pan processes where they ground up the ore and amalgam mixture for hours at a time (the Washoe Process), and for some ores that did the job.
