Mar 05 2020 · To study the depression effects of NaCit in detail the floatability of apatite at pH 80 and pH 105 were also investigated by flotation experiments as shown in Fig 3c At pH 80 NaCit has little depression effect on apatite flotation when the dosage was less than 400 mgl
The results obtained for the pH dependence of flotation of calcite using 10 4 kmolm 3 potassium oleate at two levels of pH Interestingly flotation at the minimum is found to increase from about 25 to 85 with increase in KNO3 from 0 to 3 x 102 kmo1m3
1 day ago · The flotation separation of apatite and calcite can be achieved with polyepoxysuccinic acid using sodium oleate as collector Benchscale flotation experiments show that a good flotation index with a P 2 O 5 grade of 3274 and a recovery of 8482 can be
carbonate and phosphate can be somewhat altered in the presence of one another Carbonate and phosphate species can be expected to chemisorb on the calcite surface and thus can compete with oleate for the surface Casites resulting in flotation depression Ca on the Read More
Air was then immediately introduced into the pulp to float the carbonate gangue minerals leaving the upgraded phosphate particles suspended in the flotation cell Phosphate Flotation This procedure was applied only on the highly siliceous South Florida and Western US ores In these tests the cell products obtained from the carbonate flotation step was conditioned for three minutes with 05 kgton sodium silicate to depress siliceous gangue
Reverse flotation of carbonate gangue using fatty acid with depression of the phosphate mineral is one of the more promising selective separation techniques that have been tried by several researchers Zheng and Smith 1997 Guimaráes 2005 Antony 2006
calcite depression in phosphate flotation carbonate depression in flotation flotation routes for a phosphate ore bearing silicatecarbonate gangue ii calcite flotation in the presence of carbon
Flotation of phosphate Phosphate ore is the most important source of phosphorus in fertilizers To supply the phosphoric acid plant with phosphate a high grade of phosphorus is essential as well as reduced levels of impurities such as magnesium iron and aluminum oxides Flotation is one of the key beneficiation methods
