Our spiral separators for heavy minerals, including iron ore, chrome, mineral sands and other high-density minerals, separate particles in the size range 1.5 to 0.04 mm. We have 3-turn, 5-turn and 8-turn spirals with high-, medium- and low-gradient profiles. iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
Extraction and beneficiation methods of gold ores and minerals. In gold ore processing equipment, there are a lot of beneficiation and extraction method of gold ore mine production line.For example, between heavy tinea leaching, extraction of amalgamation and so on and their mixing process, wherein the flotation method is an important separation means. Direct shipping of high grade iron ore, because of depletion or partial depletion of reserves, or high costs of operation has forced operators to use some means of beneficiation to produce an acceptable product with the lower grade iron ore reserves. Deposits of comparatively lower grade iron ore that remain relatively untouched or by-passed, are now most important because of increase in ...
The most difficult particles to gravity concentrate are the fines, and 75 microns to 2 microns are definitely very fine.
