What is a concentration of ores? Chemistry Q&A

Concentration of ores. The process of removing the impurities (gangue) from the ore is called the concentration of ores. It is also known as ore enrichment which helps to increase the percentage of metal in the ore. Methods of concentration of ores. Leaching; Froth flotation method; Magnetic separation; Hydraulic washing

Calculating Cyanide Consumption

Computing Cyanide Consumption of a laboratory leach test may be done as in the following example: Ore taken, 250 grams. Ratio of solution to ore, 3:1 = 750 cc: 250 grams. Cyanide strength, 0.3% KCN. Or when working on the metric system, Ore taken 200 grams, ratio of solution to ore 3:1 = 600 cc: 200 grams, cyanide strength 0.3% KCN
