This chapter discusses beneficiation processes for various tin ores. There are three main methods used for beneficiation of tin ores: physical concentration including gravity concentration, magnetic separation, and electrostatic separation, flotation, and a combination of gravity preconcentration and flotation.
The cyanidation process has become one of the most used methods for the recovery of gold from ores. The use of cyanide leaching for gold recovery is based on gold's properties, whereby gold does not become oxidized at ordinary temperatures.

Definition of "Beneficiation": This is the second step in the mining process, after removal of the ore from the ground. Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other. No chemical changes to the minerals are made at this point in the mining process.
A beneficiation procedure for possible refractory uses of Bitlis Massif (Turkey) kyanite ore has been developed and involves grinding to d80 = 0?106 mm, de-sliming, mica flotation, iron oxide...
The presence of clay or other slime-forming minerals—which are classed as "interference" substances—reduces the effectiveness of most combinations of reagents and in many cases inhibits flotation.

These assets give the company the ability to produce close to 150,000 tons of highly purified Kyanite every year (and to turn roughly 25,000 tons of that into high quality Mullite). The …
negative impact on the economics of the production process. Thus, the elimination of wet beneficiation and its replace-ment by dry beneficiation is an important problem in the pro-cessing of kyanite concentrate. The main method employed in Russia for the benefici-ation of kyanite ores is based on flotation and entails the use
Kyanite is produced in commercial grades using several mineral processing methods, such as hand sorting, gravity separation, magnetic separation, flotation, and roasting [ 5, 6, 7, 8 ]. Because kyanite properties are becoming increasingly complex, flotation is widely applied for kyanite beneficiation.
beneficiation techniques including: • Scrubbing • Crushing • Gravity and magnetic separation • The JKTech Drop-Weight Test measures Selective flocculation • the apparent breakage function of the Flotation SCRUBBING Scrubbing is the process whereby clays, slimes and any potential oxidization present in or on the ore typically using water.
