The Recovery of Fine Cassiterite from Metasedimentary Rock

liberate some of the cassiterite from other gangue minerals without producing high percentage of fines. Sandy (2004) [8] suggests that maximising recovery is done by targeting recovery in a certain size fraction or fractions with the highest value mineral loading. In this study the −600 µm size range of

Cassiterite Flotation - Tin Oxide - 911 Metallurgist

06-07-2015  When it comes to flotation of a Tin rich ore like cassiterite, collector is a most important reagent as it determines froth grade and recovery. The optimum addition is controlled by several factors; ore type, head grade, product grade and recovery. The collectors used in cassiterite flotation often have an effect on the froth properties.

Cassiterite - an overview ScienceDirect Topics

Primary tin deposits are mined by normal hard-rock mining methods. The ore typically contains cassiterite and sulfide minerals, and this is treated by crushing, grinding, sulfide flotation, and recovery of cassiterite by both flotation and gravity concentration (using spirals, shaking tables, and heavy-medium separation).

01-11-2019  If miners are reluctant to install riffles and increase the sluice angle, cassiterite recovery may be increased by the use of a pinched sluice box, which effectively alters the velocity of the particles along its length. At the discharge point, splitters collect the particles that were stratified by the descending flow (Wills and Finch, 2015).

06-07-2015  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.
