Calcite Processing by Flotation for Beneficiation
FLOTATION OF CALCITE The tailings from the impurity flotation section is conditioned with fatty acids such as oleic and reagent 708, the latter a vegetable fatty acid Calcite is activated and floated into the froth concentrate while the sericite, quartz, and other silicates are depressed and rejected into the flotation tailing Calcite (CaCO 3), a carbonate mineral, is one of the major gangue minerals in bastnaesite deposits The existence of calcite in bastnaesite concentrate will significantly increase acid consumption in leaching process and decrease the purity of REE in solvent extraction procedure Therefore, it is essential to remove calcite from bastnaesite concentrate during flotation processFlotation separation of bastnaesite from calcite using R a represents the recovery of cassiterite in flotation concentrate and J b represents the recovery of calcite in the flotation tailing As shown in Table 1 , when SHA was used as the collector, the SI value in the presence of CMC was a bit lower than that without CMC, indicating that CMC has a good selective depressing effect on calciteSelective Flotation of Cassiterite from Calcite with
Value added industrial minerals production from calcite
calcite flotation was performed by using tallow soap or saponified naphthenic acid collector in alkaline conditions, then the calcite tailing was treated with sulfuric acid a fter the calcite tailing treatment, feldspar was floated using the collector ANP14 (amine) Flotation experiments illustrate that PASP can selectively inhibit calcite but exert little influence on fluorite flotation In the real ore containing 2012% CaF 2 and 671% CaCO 3 , a concentrate containing 9356% CaF 2 with a recovery of 5782% is obtained in the closedcircuit flotation testFlotation separation of fluorite from calcite using 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 that22 Flotation of Niobium
The flotation separation of fluorite from calcite using
Flotation tests were performed on a mixture of fluorite and calcite (2:1 of mass ratio) to verify the selectivity of HPS at pH 85 As shown in Table 2 , the CaF 2 grade of concentrate was nearly the same as that of feed using NaOl alone, suggesting that separation of Calcite is one of the most common and important components in sedimentary rocks And calcite is an extensive carbonate gangue in the flotation of rhodochrosite, smithsonite, celestite and apatite,, It is easy to enter the rhodochrosite flotation concentrate because of naturally hydrophobic, thus reducing concentrate gradeEffect of calcium ion on the separation of tailing of this plant has a high grade of carbonatic minerals, mainly, calcite (Ca(CO3)2) and dolomite (CaMg(CO3)2) The calcite and dolomite minerals are widely use in the construction, pharmaceutical and agriculture industry Dolomite and calcite are sattype minerals that show similar flotation behaviors due to the same characteristicTECHNOLOGICAL CHARACTERIZATION OF PHOSPHATIC
