Based on the properties of silica sand from gold ore tailings, several experiments, such as flotation of sulphide ore, separation of calcite and dolomite, flotation of mica and feldspar, acid leaching tests, were researched in the flotation experiment. the results showed that with series optimum conditions,sio298.12 was got with 50 productivity for raw ore with al2o3 1.00 ,fe2o30.10 ...get price
Flotation of calcite. natural calcite deposites contain various types of silicates and graphite. for applications such as paper fillers, the calcite has to have a low grade of silicates as well as a high brightness. in addition, very low amounts of graphite are detrimental to the brightness.get price
2018618ensp0183enspcassiterite is the most common and important tinbearing mineral, and calcite, a primary gangue mineral is generally found in tin deposit. the flotation separation of cassiterite from calcite remains a challenge due to their similar response to traditional reagents. in cassiterite flotation, sodium oleate naol and sodium silicate ss have been widely used as a collector and a depressant ...get price
Abstract. this paper aimed to evaluate different depressant in pure mineral calcite and silica, through flotation test. the reagents used were sodium oleate as collector and sodium silicate as depressants and sodium hydroxide as ph regulators of flotation studies it has been observed from the size analysis that, that the liberation of calcite and silica is greater to some extent in the finer sizeget price
The flotation separation of scheelite from calcite is problematic, where sodium silicate modified by polyvalent metal ions has shown some advantages for selective depression. in this study, an alna2sio3 polymer was used as the depressant for the flotation separation of scheelite from calcite using a lead complex of benzohydroxamic acid pbbha as the collector.get price
