AMD® XRT Sorting Upgrades Iron Ore Grade from 25% to 55% at Customer Site

Challenge

In the competitive iron ore market, maximizing resource recovery while minimizing downstream processing costs is critical. Our customer, a mining operator facing declining head grades, needed an efficient solution to pre-concentrate their run-of-mine ore.

The raw ore at the site had a low grade of approximately 25%, with valuable iron minerals interlocked with barren waste rock. The customer’s existing traditional beneficiation methods were struggling to handle the volume efficiently. They needed a dry, high-capacity sorting solution to reject waste rock early in the process, thereby reducing the tonnage sent to the grinding and milling circuits and lowering overall operational costs.

Solution

The system operates seamlessly through four key stages:

Feeding Belt: Raw ore is evenly fed and spread into a single layer for accurate scanning.

Sorting Section: High-resolution sensors analyze each particle, and precision high-speed air jets eject the targeted waste rock.

Concentrate: The high-grade iron ore is collected for downstream processing.

Tailing: The rejected waste rock is discharged, requiring no water.

Results

The implementation of the AMD XRT sorter delivered outstanding results for the customer. The machine successfully achieved a massive upgrade in ore grade while maintaining minimal loss of valuable material.

As demonstrated in the actual site results:

Raw Ore Grade: 25%

Concentrate Grade: 55%

Tailing Grade: 3%
