Jun 05, 2017 · Deslimed chromite ore was floated at pH 1.5 to 5.5 using a long-chain fatty-acid collector and soluble fluoride ions as a silicate depressant. The Havens method was later modified slightly to permit flotation without preliminary desliming. This was …

May 01, 1996 · This suggest the selective separation of chromite at pH below 3.2 by using fatty acid based anionic collectors. The flotation experiments confirmed that increasing pH is harmful for the selectivity. The best results in terms of recovery and selectivity were obtained by using F2874 as a …

Jun 08, 2016 · Soaps, fatty acids, and amines are commonly used for non-metallic minerals such as fluorspar, phosphate, quartz, felpsar, etc. Promoters are generally added to the conditioner ahead of flotation to provide the time interval required for reaction with the pulp
Amines or fatty acid collectors are normally used for this sort FLOTATION BEHAVIOR OF SUDANESE CHROMITE ORES,2014-6-28 · The flotation process is typically conducted by adding 0.5 to 5.0 pounds fatty acid, 0.1 to 10.0 pounds soluble fluoride ion and 1.0 to 11.0 pounds sulfuric acid per ton of ore to the aqueous treatment medium containing the
The effect of surface potential on the flotation of chromite.

Fatty acids have been used extensively in the flotation of chromite ores. flotation machine for procesing chromium ore. process flowsheet development for beneficiation of nickel ore. Some amounts of magnetite and chromite exist in the ore together with metal values are traditionally recovered from ores by mineral-processing, smelting, and . 6
Effect of Particle Characteristics on Fatty Acid Flotation of Florida Phosphate Rock. Volume I: Project Summary 02-173-236v1Final. Abstract. Variation in feed quality from day to day, shift to shift, even from dragline to dragline, represents a challenge to beneficiation plant operators and reagent suppliers.

The phosphate collectors have been used in the flotation of calcite , perovskite, ilmenite and rutile, chromite , wolframite , magnesite , smithsonite , bastnaesite , and quartz . The price of phosphate collectors is as low as the typical fatty acid collector . For this reason, barite flotation using lauryl phosphate as collector was studied
Flotation: commonly used collectors are fatty acids (oleic acid, sodium oleate), the slurry regulator is sodium carbonate, the inhibitor is sodium silicate, the activator is sodium sulfide and heavy metal salts (zirconium chloride, ferric chloride). Oxalic acid is also used to adjust the pulp to acid and flotation with amine collectors
