QUANTITATIVE ANALYSIS OF GOLD CONCENTRATE

2018-6-17  Concentrate is a product which is the result of concentration of the ore/seed, in this case is meant copper containing approximately 30% copper, but also contains high grade gold and silver. The gold content varies between 20 - 70 ppm, while silver is about 60 - 100 ppm. Preparation of concentrate sample is drilling and blasting to

Analysis of Copper-Gold Ore

2021-11-3  Analysis of Copper-Gold Ore. Mining plants require various samples of the metals extracted from ore to be routinely analyzed, including the feed (crushed ore), the tails (waste ore left over after processing) and the concentrate (the final product). Metals requiring analysis at a copper-gold mine do not just include copper (Cu) and gold (Au).

Gold-Copper Ores - ScienceDirect

2016-1-1  1. Introduction. The association of gold and copper mineralization in commercially viable ore is a common occurrence. At one end of the spectrum is the predominantly copper ore, which contains levels of gold mineralization. This would be uneconomic to mine for its gold content, but the gold provides a significant opportunity value.

Ores Article about Ores by The Free Dictionary

The ratio between ore and vein minerals varies greatly, depending on the metal and the given deposit. For example, in veins of gold-bearing quartz the amount of gold relative to the mass of the quartz is thousandths of 1 percent. On the other hand, some types of iron ore consist entirely of ore mineral (magnetite, hematite).
