flotation cell. The required mass of nickel-copper sulphide ore material ground to 70% passing 75 m was weighed and placed in the flotation cell. This was followed by the addition of distilled water to about 60% of the cell volume before the required volumes of 1% solutions of the collector; SIPX (sodium isopropyl xanthate) and depressant were added. The additions of the …

Flotation ore dressing Britannica

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

Flotation Process Development and Assessment

Nov 03, 2015 An evaluation of the modal analyses performed around this copper flotation circuits revealed the following: During the plant survey the copper rougher circuit recovered about 60% of the copper, 20% of the lead and 5% of the zinc into the rougher concentrate. Most of the remaining copper and lead was recovered into the scavenger concentrate.

Flotation Archives Metallurgist amp Mineral Processing

Copper Gold Sulfide Ore – Flotation & Cyanidation Tests Grinding the ore to minus 100-mesh gave satisfactory liberation of the minerals. Standard flotation procedure with potassium ethyl xanthate, cresylic acid, and lime produced good-grade copper concentrates with over 85 percent recovery of copper and about 60 percent recoveries of gold and ...

Continuous Flotation Testing To Recover Cobalt From

made to feed directly into the No. 1 cell of the flotation sec tion or into an attritioner and then into the No. 1 cell. The flotation section included six Hazen-Quinn, sub aeration cells in the series. These were No. 5 units with an effective volume of 0.25 ft3 per cell. Later, seven Fagegren type cells were used as roughers.

New Eco Friendly Xanthate Based Flotation Agents

An optimal laboratory two-step procedure was developed for sodium/potassium O-alkyl carbonodithioate (sodium/potassium alkyl xanthates) production in the form of aqueous solutions. Sodium isopropyl xanthate (Na-iPrX), as the most effective salt in a real ore flotation process, was also produced at an industrial level and introduced as a collector for copper ores.

Froth flotation chemeurope.com

Froth flotation is a selective process for separating minerals from gangue by using surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement.
