Phosphate Beneficiation. Market Specifications Bone phosphate of lime, 70 to 72 per cent, common. Bone phosphate of lime 72 to 77 per cent, premium. Production Problems. Phosphate rock being a low-priced material is produced as near the fertilizer market as possible and haulage costs determine production.


The most desirable grades of phosphate rock, those with the highest BPL, are now scarce. BPL is the short name used in the art for bone phosphate of lime, or tri-calcium phosphate. Phosphate rock with a BPL concentration of 75 or higher were available and used some years ago for industrial manufacture of the end products referred to above.
