calcite flotation tailing

calcite flotation tailing - na-stawach

29.12.2021  flotation tests to recover scheelite from tailings failed due to the dilution of the concentrate by calcite. Hence to adopt the flotation process successfully, it is necessary to depress the calcite selectively which is not achieved easily(2) due to the presence of small amounts of Ca, Mg and Fe salts and the lean grade of the ores to be treated.

Selective Flotation of Cassiterite from Calcite with ...

Cassiterite is the most common and important tin-bearing 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

Calcite - an overview ScienceDirect Topics

The calcite flotation tailing in most cases is pretreated before niobium flotation. The pretreatment reagents used include acids, such as sulphuric acid and hydrochloric acid. Studies conducted on carbonate flotation tailing on the Orca (Canada) ore [3] showed that the use of hydrochloric acid in the pretreatment stage improved niobium metallurgy significantly.

15.11.2013  The flotation tailing mostly consists of quartz and clay with very little amount of calcite. This is evidenced by the presence of trace amounts of Ca in the tailing, which may be due to fine intercalation between quartz/clay and calcite. Electron micrograph of tailing also shows the interlocking of quartz grains with clay. Significant amount of aluminium (Al) is due to

01.01.2018  The flotation tests were used to examine the flotation regularity of rhodochrosite and calcite in the absence and presence of Ca 2+. To clarify the reasons on the difficulty in flotation separation of rhodochrosite and calcite, the electro-kinetic zeta potential measurements, solution chemistry calculations, scanning electron microscopy, accompanying

Flocculation of flotation tailings in presence of silicate ...

13.08.2018  Flotation tailings were successfully flocculated in the presence of cationic polyacrylamide and silica gel. The effects of various parameters such as polymer weight, charge density, and pH on the rate of flocculation were also investigated in the current study. The flocculation mechanism of the flocculant on tailings was investigated using zeta potential and

16.09.2014  The underground extraction of Pb-Zn mineralization in the Touiref area stopped in 1958. A large volume of flotation tailings (more than 500 Mt) containing sulfides were deposited in a tailings impoundment. The goals of this study are to evaluate the neutralization capacity of the unoxidized and oxidized tailings, to assess the speciation of metals between the different

Column Flotation Testing Better Improved Recovery

21.10.2017  Calcite behavior during column flotation was particularly interesting because the flotation response of calcite mirrored that of the collected fluorite and that of the rejected silica at different points within the column. Calcite concentrated with the fluorite in the lower three column benefieiation zones. Calcite rejection was accomplished in the froth phase cleaning zone.
