HOT is the leading manufacturer of High Quality Phosphate Ore Flotation Equipment and 3D disigner of phosphate production line.Characteristics of phosphate rock resources Phosphate composition is complex.Sedimentary phosphate is dominant In phosphate rock resources.Different types of ore beneficiation degree of difficulty and process are quite different,due to the ore-form.
Read More1983-3-22This invention is directed to a novel process for the flotation of phosphate ores, to recover phosphate ore as the concentrate. It is a type of flotation known as reverse flotation, since the tailings quartz or silica particles are floated, and the desired ore, namely phosphate rock particles, sink and become the concentrate.

Read MoreThe recent development of phosphate flotation collectors was reviewed.A simple classification for flotation collectors was introduced according to the composition of collectors and ionic characteristic and other aspects,and recent progress in phosphate flotation
Read More2019-12-14The effect of collector type on concentrate grade and recovery was investigated using the highly siliceous phosphate ore. Carbonate flotation of this ore at pH 4.5, using sulphuric acid as pH regulator, was carried out with three different collectorsoliec acid, tall oil and OA-5 a sodium salt of sulphonated oleic acid.

Because of the increasing world demand for phosphate, P 2 O 5 content of the ore is gradually falling, and it is becoming economical to mine and beneficiate many lower-grade deposits El-Jalead et al., 1980.
Read More2014-7-16The ore is a volcanic phosphate ore containing approximately 20 P 2O 5 27 to 28 CaO primarily as apatite. Principal impurities are barite 9 to 15 BaSO 4, hematite 19 to 20 Fe 2O 3, alumina and silicates occurring as quartz, micas and clays. The barite is removed in a pre-flotation step using cetyl stearic sulphate as a collector.
Read MoreSolutions for Direct and Reverse Flotation. 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.
