The importance of flotation separation has long been, and continues to be, an important technology for the mining industry, especially to metallurgical engineers. However, the flotation process is quite complex and expensive, in addition to being influenced by many variables. Understanding the variables affecting flotation efficiency and how valuable minerals are lost to the tailings gives.Before the new tailings pond construction completed in 2002, there are 90000 tons of tailings with recoverable tailing with high gold content in the old tailings pond. The gold content is about 1665 kg, and the silver content about 25 tons. Xinhai carried out industrial practice in handling tailings with the original 250tpd CIP plant.

Environmental Impact Variability Of Copper Tailing

Environmental Impact Variability Of Copper Tailing

Copper sulfide can be divided into single copper ore, copper sulfur ore, copper-molybdenum deposit, copper nickel, carrollite and so on. Basically, only flotation can be considered in its separation. Almost all copper sulphide ores contain iron-bearing sulfides, so in a sense, the flotation of copper sulfide is essentially the separation of.These provide ore to the plant, that, after comminution, is sent to a set of flotation cells producing the copper concentrate and pyrite-rich tailings that are deposited in the nearby tailings impoundment. This covers an area of about 50,000 m2 in the valley of a small stream tributary of the Fan I Madh river.
