How to Separate Copper from Lead by Cu Depression
How you separate Pb from Cu depends on how much of each metal is present. You best depress the metal that’s the most present, the metal you have the most of & you float the metal you have the least of. In this case, flotation of a small amount of lead from the copper concentrate would […]
Sequential Copper–Lead–Zinc Flotation
To improve the selectivity between copper and lead, a sequential copper-lead-zinc rougher circuit was tested. Each of the rougher circuits had a dedicated regrind and cleaner circuit. The advantages of the sequential circuits are that the levels of selectivity can be increased, particularly for copper and lead. With this process, copper was recovered first with MBS depression of lead, […]
Determine Total Cyanide in Solution
The test outlined is a simple and rapid method for the determination of total cyanide in plant solutions, providing significant amounts of iron cyanides are not present. Copper, nickel, zinc, and iron cyanides build up in plant cyanide solutions as a result of the usual gold milling practice of recycling solutions . Since these metals […]
Itronics will update the procedures used in Au-Ag-Cu mines
The company Itronics Inc. has recently announced it’s updating its technology developments and plans “with a focus on potential applications for silver-gold mines that have a silver to gold ratio exceeding 4 to 1 in the ore”, it’s possible to read on the firm’s website. According to the Nevada-based business, its technology may also “prove to […]
