Antimony Ore Crushing Raw Material to Refined Concentrate
Concentration Processes. Once the ore is crushed, the next step is to increase the concentration of antimony, separating it from unwanted materials. 1. Gravity Separation. Antimony's high density (6.68 g/cm³) makes it ideal for gravity-based concentration methods.

Pre-concentration at crushing sizes for low-grade ores processing – Ore
As pre-concentration at crushing sizes depends on the ore texture and consequently, it relies on the achieved mineral liberation degree, a straightforward methodology to assess quantitative mineralogical data of the ore macro-texture, based on image analysis, was developed.

Methods of concentration of Ores – Gravity Separation.
The ore particles are crushed into a fine powder and are then added to water that forms suspension to which collectors such as pine oil, fatty acids, etc., and froth stabilisers are added. The collectors boost the metal particles of the ore's non-wettability, making the powdered ore form a froth on the water's surface.

Iron processing
Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue.

Crushing, Grinding and Concentration of the Ore
(1) Crushing and Grinding of the Ore. The ores occur in nature as huge lumps. They are broken to small pieces with the help of crushers or grinders. These pieces are then reduced to fine powder with the help of a ball mill or stamp mill. This process is called pulverisation. (2) Concentration of Ore or Ore Benefaction
