CN103157558A - Beneficiation method of recovering sulfur

The invention belongs to the field of mineral processing, relates to a beneficiation method, and particularly relates to a method of sorting copper sulfide ore flotation tailings. The method comprises the following steps: A, the tailings with copper and sulfur separated are dewatered through a thickener, wherein the content of the sulfur in the tailings is more than 20%, and the concentration

Improvement of copper–molybdenum ore beneficiation

Jan 01, 2013 1. Introduction. A significant part of copper and molybdenum losses (about 15%) during copper–molybdenum ores beneficiation is associated with the middlings cycle where mineral fractions with a comparatively high content of valuable components and low floatability are accumulated , .Middlings fractions are considered as the most suitable product for the application of a combined flotation

Copper Flotation Plant Lab Flotator

Copper flotation beneficiation plant design. Flotation is a benefication method based on the hydrophobicity difference of the mineral surface.While the copper mineral is usually in the form of sulfuration exiting in the mineral.Its natural floatability is good, so flotation is the main method of extracting the copper ore

The beneficiation process of nickel ore,copper-nickel

Sep 24, 2020 The main method for beneficiation of copper-nickel sulfide ore is flotation, while magnetic separation and gravity separation are usually auxiliary beneficiation methods. When flotation of copper sulfide nickel ores, collectors and foaming agents for flotation of copper sulfide minerals are often used. A basic principle for determining the
