Magotteaux mining grinding beads ceramic
Maximum recovery at a minimum cost
Background
Ernest Henry Mining wanted to alter the pulp chemistry to improve the flotation performance in its plant.
Our innovation team has developed a range of premium ceramic grinding beads specifically designed for fine and ultra-fine grinding purposes. These beads offer exceptional quality, catering to your specific needs, pushing the boundaries of precision and performance.
Solution
After a series of promising laboratory test work, the decision was taken to convert the ball mill media charge from forged steel to high chrome media.
Results
The improvements in the pulp chemistry resulted in an increase in copper and gold recovery of at least 1.3% and 1.0%, respectively. The additional copper in concentrate production reached up to 1430 tpy and 2840 ounces of gold per year, representing a $12.8 million USD increase in gross profit. Additionally, laboratory test work also indicated that the use of high chrome media could lead to reductions in pH during rougher, which would see no negative impact on the plant’s performance. In fact, once applied, this strategy realised an annual cost saving of $700,000 USD by reducing lime consumption.
