With the Machine invented by Akashganga, these impurity is separated and concentration of the ore increase.

Flotation tests were conducted in a single flotation cell (XFD of 0.75 L and 1 L) with adding sodium sulfide (Na2S) as sulfurizing reagent, carboxymethyl cellulose (CMC), sodium hexametaphosphate
Contact Us2005101ensp;0183;ensp;The methods presently used in the industrial flotation of iron ores are direct flotation (where iron minerals are the froth product) and reverse flotation (where quartz is the froth product). There are reverse anionic and cationic flotations for the removal of silicated gangues from iron ore ( Uwadiale, 1992 ).
Contact UsThe pneumatic cell has a great potential for quartz reverse flotation in the iron ore industry, with the possibility of reducing the flotation time and increasing the metallic recovery. One stage of pneumatic flotation can replace the rougher and scavenger stages of mechanical cells, with a strong decrease in the footprint and enhanced
Contact Us201212ensp;0183;ensp;With the depleting reserves of highgrade iron ore in the world, froth flotation has become increasingly important to process intermediate and lowgrade 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.

Contact Us01 One. The common quartz mining processes. Usually, there are iron oxide, clay, mica, organic impurities, etc., in the quartz stone except for SiO2. The purpose of the quartz mining process is to remove a small amount or trace impurities in quartz stone, then obtain the refined quartz stone.
Contact Us2016310ensp;0183;ensp;The presence of slime in the ore slurry affects the cationic flotation of quartz. In order to improve the efficiency of iron ore flotation, Tao et al. (2010) have used a depressant for clay and iron minerals. The depressant, known as GP clay binder, reduces the coating of slimes on quartz and hematite particles.
