Mining Carbon Depressant D481 for Mineral Processing

Introduction

It mainly used for non-ferrous metal ores containing carbon, fine-grained graphite and cryptocrystalline graphite. It can effectively inhibit the entry of carbon-containing minerals into the tailings, avoid its unfavorable interference on flotation, and improve the grade and recovery rate of the concentrate.

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;
