ActivePhosphate rock and concentrate--Determination of acid insoluble content--Gravimetric method
磷矿石和磷精矿中酸不溶物含量的测定 重量法
Application Summary AI generated
This standard specifies a gravimetric method for determining the acid-insoluble content in phosphate rock and concentrates. It is applied in the mining and mineral processing industries for quality control and classification of phosphate ores, particularly to assess the level of siliceous or other non-phosphate gangue materials. The method is used during ore beneficiation and product evaluation to ensure the concentrate meets specifications for fertilizer production.
