Introduction of five flotation process chemical and pharmaceutical

Kwu soil containing iron phosphate, alumina and other impurities. Hard rock bed most of the high-grade phosphate deposits, mined from these deposits of phosphate ore sorting Needless to add 512 can be sold directly. After the first phosphate ore coarse sieve to remove waste rock, followed by flushing clean as thoroughly as possible with the clay mineral mud and then by crushing and fine grinding to achieve dissociation. Florida phosphate rock produced by most of the phosphate rock, and with 31 ~ 36% P2O. 】 2. Selective flotation of quartz carved from selected phosphate, used as a fatty acid collector. In order to remove adsorbed on the surface of fatty acids in the phosphate caustic alkali or ammonia can be added to the slurry of fine pre-saponification, or high concentrations of mixing. In the flotation process can be added the right amount of fuel oil in order to reduce the amount of fatty acids expensive to achieve the desired recovery. In order to remove impurities of quartz and mineral mud, phosphate selectivity of the primaries do not have too strong, general, and selected phosphate minerals than other more complex selection, because the associated gangue minerals surface with a protective layer and has a certain activity, for which it is necessary to add sulfuric acid or acid pickling to remove fluoride on the surface of primary ore collector is available in the selected amine collector in the selected quartz float . - Phosphate primary collector used a fatty acid (400 to 1000 g / t) and fuel oil debate (500 to 200 g / t), mixing time of 5 to 8 minutes, 3 to 6 minutes flotation pulp density 20 to 30% solids. Off oil processing requires sufficient quantities of sulfuric acid or a fluoride acid. Need to add amine flotation of quartz collector (5o ~ 1O0 g / t) and kerosene (25 to 150 g / t), 3 to 6 minutes flotation time, pulp density of 25 to 30% solids shown below is the process of a phosphate processing plant.

I ÷ + fine gravel coarse concentrate ore concentrate most of the potassium potassium potassium salt rock salt by potassium chloride (23%) sodium chloride (72%) and other impurities (4%) composition. In the earlier election of sodium chloride from potassium chloride in the float to join the lead or bismuth ion activation, then add the organic anion selected pharmaceutical and fat broken floating sodium chloride, potassium chloride in the pulp left Tuo can get up to 60% K0 grade of concentrate, but the flotation process of high pharmaceutical consumption, not the economy now, the world's potash processing plant they use the opposite process , that is, first elected floating potassium chloride. (K rock salt), and rock salt left in the slurry application. potash ore by crushing and dry-grade sodium chloride and potassium chloride was added wet to the solutions saturated solution from the particle size (a 4 +65 mesh), followed by adding clay inhibitor according to ore grade and flotation reagent mixing starch slurry concentration of 50 to 75% solid content, the collector used aliphatic amines are Peter (c6 ~ c24 carbon chain), the amount of 14-250 ~ 1000 g / t: foaming agent used is poly L-: alcohol, fuel oil can be added to control foaming. Finally, flotation, solid homes slurry concentration 2035% volume, l flotation time three minutes or four minutes, then the selection of primary concentrate, and ultimately saturated with potassium chloride concentrate solution or water, rinse and dry. potash flotation sludge inhibitors commonly used in starch, guanidine Seoul bean gum, dextrin, polyethylene glycol and polyacrylamide high molecular weight polyethylene glycol is best, but the impact of bubbles. In the flotation process, such as excessive blistering phenomenon, can be added, ~ MIBC (methyl isobutyl alcohol) in order to achieve better selectivity is shown below into the flotation of potash ore pretreatment process. rod mill sieve materials (a mesh ),。。: a cyclone 8 control one thousand one hundred eleven (+1 \Dayton machine - a 'l J a 27GVlt one by one one by one at +250: ...
