This work studied the effects of sodium hexametaphosphate (SHMP), tanning extract, water glass (WG) and calcium lignosulfonate (CLS) as depressants for the separation of smithsonite from calcite by using a cationic collector called octadecylamine acetate (ODA). Micro-flotation experimental tests showed that CLS can greatly and …

fluorspar ores containing in addition to fluorspar values appreciable quantities of sulfide minerals may be concentrated to produce a fluorspar enriched concentrate having a fluorspar concentration of at least 97% by a single step selective froth flotation treatment of aqueous pulps thereof provided the pulp is conditioned prior to its collection under …

The present standard defines gravimetric determination method of flotation agents in fluorspar used in the production process of hydrofluoric acid. The method spreads for those products, which were subjected to flotation processing with equal or more than 0.002 % mass quantity of flotation agents in dry material. 01.01.1993

Alternative processes have been proposed for selective separation of fluorite and gangue minerals (carbonates and silicates) present in fluorspar ores. Calcination and gravity …

Fluorspar Beneficiation by Packed Column Flotation. Acid-grade fluorspar is utilized in the production of hydrofluoric acid from which a variety of organic and inorganic fluoride chemicals are made, including synthetic cryolite and elemental fluorine. The manufacture of chlorofluorocarbons (CFCs) is the volume leader in the …

Haematite can be beneficiated from the fluorspar tailings using reverse flotation. DDA is a more selective collector for silicon as compared to Betacol. 300g/t of DDA, 400-500g/t of starch and natural pH of 8 – 9 gave the best results of 60.8% Fe and 2.83%Si in the sinks.

Optimal fluorspar flotation was achieved under the following conditions: 3.6 g/kg of sodium oleate as the collector, 2 g/kg of sodium silicate as the pH modifier and …

Sulfate minerals have gradually become the main gangue minerals of fluorite deposits, and the flotation separation of fluorite and sulfate minerals is difficult with commonly used depressants. In this paper, the high selectivity of a novel depressant sodium polynaphthalene formaldehyde sulfonate (SPS) for the flotation separation …

In this case selectivity of collector in flotation of Fluorspar especially in presence of Calcite can be improved. 3- For depressing of calcite and dolomite (using Quebracho) could be useful; and ...

Large reserves of feldspar ore exist in the Aegean region of Turkey. The main colored impurities in these ores are iron- and titanium-bearing minerals such as anatase, rutile, sphene and ilmenite. In this study, a potassium feldspar ore containing mainly quartz and coloring impurities was subjected to beneficiation tests involving magnetic …

The results demonstrated a high selectivity for the flotation of calcite from fluorite using this new reagent schedule. The best selective separation for a single mineral and mixed binary minerals was obtained when 200 mg/L of NaF, 50 mg/L of CA, and 6 mg/L of SOA were used at pH 9. In addition, a batch flotation experiment was carried out ...
