The test conditions under which the flotation tests were conducted can be seen in Table 1. For test 1, Lilafloat was used as a collector while in test 2, ACCOPHOS-950 Cytec was used as a phosphate depressant in conjunction with Lilafloat collector. In test 3, the collector system comprised of EDA and SM15, a phosphoric acid ester.
In the reverse flotation, Cytec Acco-Phos 950 depressant 20-100 gt minimizes phosphate loses into the silica froth product using amine collectors. In the treatment of sedimentary pebble phosphates, Aero 845 can be used in conjuction with fatty acids.
May 01, 2013 The 1 mm phosphate fraction was subjected to further grinding and then wet milled at 50 solids mass to obtain feed of 80 passing 150 m for flotation test work.The reverse flotation was conducted in order to float the silica to concentrate and depressed apatite to the tailings. The flotation test was carried out with a 150 m sample in a 2.5 L Denver mechanical flotation cell under ...
Dec 15, 2020 In that sense, the relevant parameters of phosphate ores flotation are discussed while focusing on apatite, calcite, dolomite, and quartz as main constituent minerals. Leading phosphate
Flotation of Chalcopyrite Copper Ore. In this example, the effect of different alkanol amines on the flotation of copper ore in laboratory flotation cells is examined. Samples of copper ore from Western Canada containing 500 g per sample are prepared. The ore is relatively high grade and also contains significant amounts of silica gangue.
Although normally used for the flotation of fine particles, column flotation was successfully used by the University of Florida for the flotation of phosphate from coarse feed 0.85 x 0.425-mm ...
Cytecs Aero 8651 fatty amine promer is utilized in operations running an amine float. In the reverse flotation, Cytec Acco-Phos 950 depressant 20-100 gt minimizes phosphate loses into the silica froth product using amine collectors. In the treatment of sedimentary pebble phosphates, Aero 845 can be used in conjuction with fatty acids.
A separation process is provided for treating a feed material comprising silica, feldspar, and metal impurities, including at least one of mica, iron impurities, or refractory heavy minerals, to form one or more products for use in making glass. In the process, the feed material is floated in the presence of a depressant to inhibit the flotation of feldspar and thereby form a concentrate ...
The rougher flotation test conditions were similar to those of BM-6, with the addition of ACCO-950. There was not a significant decrease in the floatability of the feldspar minerals with the addition of the depressant. The silica rougher flotation concentrate was visibly polluted with feldspar and was not submitted for analysis.
Amylose was the least effective depressant among all starches, especially for the cationic flotation system. The depressant action was a function of pH and of the relative amounts of polymer and surfactant. Alkaline pH favoured depression, whereas as the collector level was increased, the depressant action was diminished and eventually eliminated.
Increasingly stringent environmental regulations and industry adoption of waste minimization guidelines have thus, stimulated the need for the development of recycling and reuse options for metal related waste. This book, therefore, gives an overview of the waste generation, recycle and reuse along the mining, beneficiation, extraction, manufacturing and post-consumer value chain.
Additionally, a synthetic polymeric depressant ACCO-PHOS 950 was developed by Cytec. The aim is to limit apatite loss during silicates flotation using amine collectors. The reagent proved to be effective when used on North Africas high-grade phosphate ores 77 .
