There are many methods of separation (concentration) of minerals: 1) Gravity separation. There are more than 12 types of gravity separation of minerals. It is used for the extraction of gold, coal, cassiterite, wolframite, rare earth mineral, niobium, zirconium, uranium minerals, and others.
· Because of the nature of the phosphate ore, such as mineral types and content, disseminated particle size, its separation difficulty and flotation types varies. Phosphate ore is divided into siliceous phosphorite, calcareous phosphorite, and siliceous phosphorite according to the chemical composition of the minerals.The froth flotation types differ from different types of phosphate ore greatly.

Gravity Separation is used to separate mineral and gangue with a large difference in their Specific Gravities. Chromite, tin, tantalite and various heavy metals are amenable to this principle. Some gold ores contain Free Gold which can be recovered by gravity separation and this is the traditional method used in artisanal gold mining.
For chemical physical separation method, we usually use flotation process, leaching method to do gold mining. Because in the process, we will use chemical to extract gold from ore. Physical separation usually involves the difference in mass between gold and most of the other associated minerals.
chemical separation technique for mining | methods and equipments Gold Mining Methods - Ground Truth Trekking. 6 Oct 2010 A variety of specific techniques can be used for mining the ore, and "froth flotation" to perform an initial separation of gold from rock.
Essentially the technology of mineral beneficiation resides in the separation of the mineral components by the least energy-intensive means, and in many cases the solution to this is separating them by the physical rather than the chemical procedures, even if
· Separation processes—or processes that use physical, chemical, or electrical forces to isolate or concentrate selected constituents of a mixture—are essential to the chemical, petroleum refining, and materials processing industries.

Separation Techniques. A separation process or technique is a method that converts a mixture or solution of chemical substances into two or more distinct product mixtures. At least one of results of the separation is enriched in one or more of the source mixture''s constituents. In some cases, a separation may fully divide the mixture into ...
· Chemical separations involve isolating metals and minerals from their ore by chemical processes such as (for the most important ones): Solvent extraction : separation of one or more substances from a mixture by treating an aqueous solution of the mixture with a solvent that will extract the required substances, leaving the other undesirable materials behind.

The physical and physico-chemical separation techniques are needed to concentrate those products for recycling in a good way. According to physical and physico-chemical properties of different products present in urban mine, the physical separation techniques permit to separate or isolate them, for re-use or appropriate treatment or disposal.
Chemical precipitation is a conventional technology used to treat mining-influenced water MIW including acid mine drainage neutral drainage and pit lake water Chemical precipitation processes involve the addition of chemical reagents followed by the separation of
The HMF electromagnetic filters are used in wet process separation of para-magnetic minerals found in quartz, feldspar,silicates, calcium carbonate and kaolin. The flow-rates are engineered in accordance with customer requirements. These are the most technologically advanced magnetic systems that we can offer and can reach a power of 20,000 Gauss.
What happens in most modern gold mining operations is a combination of physical and chemical separation to recover the gold. The ore is ground to a certain size and passed through a stage of physical separation. When the coarse fraction of the gold is separated the fine gold is recovered by chemical means. Kali Liu.
Mining chemical use can be expected to provide even stronger growth, since the industry is faced with lower-grade ores which require larger amounts of chemical products in their processing. Increasing requirements for environmental and health protection in the industry also require increasing use of chemicals, i.e. in dust control, and the more efficient use of in many cases scarce water ...
