Heap leach agglomeration conditions

Heap leaching has attracted significant research interest as an alternative technique to process ore due to the potential competitive advantages offered by significantly lower operating and capital costs, as well as the ability to process lower grade ores.

Agglomeration is a critical pre-treatment step in heap leaching, where its main function is to improve heap permeability by combining fine particles, generated from the crushing process of the ore, onto coarse particles. This project focuses on agglomeration with an aim of investigating various agglomeration conditions, through experimental work, to optimise the copper and uranium recoveries obtained through heap leaching.

The agglomeration conditions investigated include the effect of varying acid dosage, moisture content and chloride added in agglomeration. The optimal agglomeration conditions determined can lead to a higher initial metal dissolution and thus potentially contribute to improved process economics due to higher overall metal recoveries or shorter leach cycles for heap leaching.
