(Cl. 209466) This invention relates to a process for recovering cassiterite from ores and relates especially to the concentration of cassiterite (SnO from oxidized minerals by froth flotation. Tin is obtained from ores, such as those found in Bolivia, which contain a great variety of minerals.
Typical minerals of this period are: quartz (usually in crystals), cleavelandite, lepidolite, lithia tourmaline, columbite, cassiterite, spodumene, and etched or pocket beryl. III. At Buckfield, and to a very minor degree at Mount Mica and Auburn, an intermediate phase followed during which rare lithiummanganese phosphates were deposited by the ascending solutions.
Processing of ores to produce tantalum and lithium 301 (b) Sand tailings originating from the above ore and containing sufficient valuable fine mineral to warrant reprocessing. (c) Hard rock pegmatite from the primary ore body scheduled for commencement in 1990.
Key words: fine cassiterite particle; electroflotation; salicylhydroxamic acid (SHA); tributyl phosphate (TBP); adsorption 1 Introduction Flotation of fine particles has become particularly important in recent years as advances in grinding, allowing low grade mineral deposits to be economically exploited [1−2].
Spodumenebearing pegmatites occur in a narrow belt miles long and miles wide extending southwestward from Lincolnton to Grover, N. C. According to statements judged to be conservative, the tinspodumene belt of the Carolinas contains an estimated 4,300,000 tons Of .
