Sometimes depressants are used to separate the sulphide ores by adjusting the proportion of oil to water. Such as, in case of an ore containing Zinc sulphide and lead sulphide. The depressant used is sodium cyanide. Fig. 3. Froth floatation process. Floatation stages are as follows Roughing is the first stage of floatation.
The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example FeOs SiO 2 s FeO.SiO 2 slag This is

Flotation of Nickel-Copper Sulphide Ore Optimisation of , Keywords flotation, process optimization, Taguchi orthogonal array, ANOVA 1 Introduction Froth flotation is widely used for separating base metal sulphide minerals in complex or One of the major challenges faced by the flotation of these ores is the ever varying grade and mineralogy as ...
Copper Flotation - Elmhurst College. The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime simply water and ground-up limestone to give a basic pH, pine oil yes, it comes from trees -- a by-product of paper mills to make bubbles, an alcohol to strengthen the bubbles, and a ...
floatation process images of iron ores mines. SeparationMetso. s flotation equipment such as flotation columns flotation cells and flotation machines help in maximizing the recovery of copper and other lead bearing minerals. Magnetic separators and magnetic filters on the other hand are designed especially iron ore and rare earth elements in mind.

Most of the worlds nickel is extracted from the mineral pentlandite, Ni, Fe9S8, which frequently occurs in ores containing predominantly pyrrhotite and various non-sulRdes, some of which contain magnesium Table 1. The nickel content in such sulRde ores is generally low 0.23 and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ...
Flotation on the copper ore processing All details about ... Foam flotation is a process by which collectors condition a mixture of water suspension to make the copper minerals water repellent while leaving the non-Cu minerals hydrophilic.Flotation is made from finely ground copper ore in flotation cells.The previous page explains the types of copper ore that exist and the extraction process ...
Jan 02, 2012 With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a centurys practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.
