Tin values in the form of cassiterite (SnO 2 ) are recovered from aqueous pulps of finely divided cassiterite-bearing ore, preconcentrate or concentrate by froth flotation. The ore pulps are deslimed thoroughly, partially or not at all. Slimes, gangue or waste minerals in the pulps are selectively depressed by use of a metal salt/silicate reagent combination.

For example, it was found that tin can be enriched with ...

The output of a slimy product of –20 μm is 20% with a tin content of 0.46% (according to chemical analysis). This product is one of the sources of tin losses (up to 33.5%) in the flotation concentration process and requires additional technological solutions.

The main focus of this study is to interpret the process behavior of (fine to ultrafine) cassiterite from tin tailing residues through different flotation methods.

Cassiterite (SnO2) is very friable and special considerations to crushing and grinding of the ore are necessary to avoid an excessive production of fines. ... In many cases this is a batch process using a Unit …

The Importance of pH in Flotation. In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE.
