cassiterite ore flotation

Cassiterite Flotation - Tin Oxide

2015-7-6  Cassiterite flotation is nearly always performed in an acid environment, the exact value depending on the ore source and collector to be used. Sulphuric acid is used for pH adjustment in most cases. Changes in pH can cause changes to the froth. A reduction in pH will give better selectivity but usually at a lower recovery.

Selective Flotation of Cassiterite from Calcite with ...

The development of selective collectors for cassiterite flotation is a relatively popular field . Oleic acid and its derivatives are the most widely used collectors in oxidized ore flotation [9,10,11,12]. The downside of this fatty acid collector is its low selectivity and poor solubility at low temperatures .

2017-11-1  Tin and its compounds have a variety of applications. It is recovered as cassiterite from ore deposit by flotation. Traditionally, the use of fatty acids and their derivatives with limited selectivity of cassiterite over calcite (the main gangue mineral) has been replaced by benzohydroxamic acid (BHA).BHA shows poor collecting ability to cassiterite, even when lead nitrate (LN) is added as the ...

The Practice Of Cassiterite Flotation In Bolivia

2016-9-28  One of the major problems in selective flotation of cassiterite is the presence of metal ions in solution, such as ea+2, Fe+2, Fe+3. These ions can act as activators for other minerals present in the ore. In this way, for example, quartz and silicates can be floated along with cassiterite, lowering the grade of the tin concentrate.
