Carbon Depressant D481 for Beneficiation

Carbon Depressant D481 for Beneficiation

2022-03-04

Introduction


It is mainly used in the case of non-ferrous metal ore containing carbon, fine-grained graphite, and cryptocrystalline graphite. It can efficiently suppress carbon-containing minerals into the tailings, avoiding its adverse interference on flotation, and improving the grade and recovery rate of concentrates.


Usage:


It is formulated into a 2% concentration solution and added to the flotation process as an inhibitor. The dosage is 100-500 g/ton to the ore.



Case:


In a copper mine in Sichuan, the original ore copper grade was 0.8%, the carbon content was 6%, and 400 g/ton of the inhibitor was added, the copper concentrate grade was increased from 17% to 22%, and the recovery rate was increased from 85% to 91 %, greatly improving profitability;
