Application Of Custofloat® Carbonate Collectors In Beneficiating Phosphate Ores In China, Guoxin Wang, Zhengguo Jiang, Lingyi Du Mar 2015

Application Of Custofloat® Carbonate Collectors In Beneficiating Phosphate Ores In China, Guoxin Wang, Zhengguo Jiang, Lingyi Du

Beneficiation of Phosphates VII

Custofloat® 813 (CF-813) is a collector specially designed and manufactured by ArrMazz for reverse flotation of phosphate ores with carbonate impurities. It was used to process phosphate ores from several mines in China with great success. The paper will present the process flowsheets and flotation results of phosphate ores in three commercial beneficiation plants.

Processing Florida Dolomitic Phosphate Pebble With Custofloat® Carbonate Collectors, Guoxin Wang, Zhengxing (James) Gu

Beneficiation of Phosphates VII

It was estimated that phosphate reserves associated with high carbonate minerals are greater than those with siliceous gangues worldwide. It has been long recognized that separation of carbonate from phosphate is difficult because those minerals contain same or similar alkaline earth cations which lead them to exhibit similar surface behavior in flotation. With the depletion of easy-to-process phosphate reserves, phosphate deposits with high carbonate impurities must be mined and processed to meet the demand. Crushing, grinding and flotation are considered the most efficient process to recover phosphate from phosphate ores associated with carbonate gangue minerals. Therefore, flotation reagents, especially collectors, …

A Tailor Made Approach For The Beneficiation Of Phosphate Rock, Leonid Lisiansky, Mike Baker, Keren Larmour-Ship, Olga Elyash Mar 2015

A Tailor Made Approach For The Beneficiation Of Phosphate Rock, Leonid Lisiansky, Mike Baker, Keren Larmour-Ship, Olga Elyash

Beneficiation of Phosphates VII

Tenova Bateman Technologies (TBT), part of Tenova Mining & Minerals is known as a provider of advanced process technologies in solvent extraction, phosphate beneficiation and fertilizer production.

TBT has participated in a number of phosphate projects and offers a comprehensive range of phosphate treatment technologies: from beneficiation to the production of purified phosphoric acid and downstream salts.

The beneficiation of phosphate rock can often be simplified and made more economic by taking into account the distribution of P2O5 and impurities as a function of their deportment between the size fractions resulting from mined and comminuted sedimentary phosphates. …
