Description . The Copper Ore Flotation Plant is a cutting-edge solution designed for the copper processing industry. Crafted from high-quality, wear-resistant materials, this equipment boasts exceptional durability, corrosion resistance, and oxidation resistance.
Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways. Flotation depends on ...

The feed to a copper flotation plant is 150t/h, with a feed grade of 2.5%. The filtered concentrate after 24hrs is 255 dry tonnes. Given that the grade of the material lost as tailings is 0.12% and the metal recovery was 88%. Determine how much material in tonnes is lost as tailings. Calculate the concentrate grade. Calculate the % metal loss.
After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio Table 1: Grade/recovery performance of a hypothetical copper ore flotation process.
Copper Flotation is a beneficiation method based on the hydrophobicity difference of the mineral surface. While the copper mineral is usually in the form of …
Flotation. According to the difference in physicochemical properties of mineral particle surfaces, flotation is the method that selectively enriches the target minerals in the pulp at the gas-liquid interface and separates them from the pulp, thus realizing the mineral separation. It is also known as floating separation.
Operating plant material balance purpose is to produce a picture of the state of an operating plant. An example solving a copper concentrator flotation circuit is presented.
flotation models are linked. For example, a laboratory test conducted on a drill core sample, intended to represent a portion of the orebody, is conducted at a specific grind (represented by a P 80). However, when that ore is actually processed through the plant it may well be (and in many cases most likely will be) at another P 80 ...
The various copper-cobalt ores mined by Gecamines, together with typical plant applications and results, are briefly described. Intensive laboratory investigations have been undertaken in recent years to improve the metallurgical performances of the various concentrators. As a result of these tests, it was shown that the flotation of the siliceous …
