Grade Blending for Iron Ore Processing Akumen

The grade of the ore differs across the deposit and can be well above or below the target grade range that was promised to the customer. Blending ore of high and low grade can help to hit just the target in those cases. However, two questions arise here: 1. How to blend the ore best? 2.

Iron Ore Blending Based on Linear Programming

Ore Blending is an important problem that the majority of mining enterprises have to face. To solve the ore blending problem, the production plan should be made firstly, and then small adjustments should be made in according to the actual condition. By effective control and management, the balance of ore quality and stability will be realized.
