Description

technical field [0001] The invention belongs to the technical field of phosphate rock screening, in particular to a beneficiation device for producing phosphate rock by microalgae phosphorus accumulation. Background technique [0002] Phosphate rock refers to the general term of phosphate minerals that can be used economically, and is an important chemical mineral raw material. It can be used to make phosphate fertilizer, and can also be used to make yellow phosphorus, phosphoric acid, phosphide and other phosphates for use in medicine, food, matches, dyes, sugar, ceramics, national defense and other industrial sectors. The application on the Internet has a history of more than 100 years. There are many kinds of ore dressing for phosphate rock, among which microalgae bioleaching technology is a very advanced technology. Bioleaching technology is the use of microorganisms to leaching ore, which is to dissolve the metal in the ore with the help of certain microorganisms. It ...
