The performance of mineral grinding circuits strongly affects downstream processes such as flotation and cyanidation, and grinding is often the single most expensive unit operation. Hence, optimization efforts must be made on a regular basis to maintain and improve its technical and economic efficiency. The focus of this thesis, off-line optimization of grinding circuits, is …

To liberate individual minerals trapped in rock crystals (ores) and thereby open up for a subsequent enrichment in the form of separation. To produce fines (or filler) from mineral fractions by increasing the specific surface. Grinding takes place in more "open" space which makes the retention time longer and adjustable compared to crushers.

Using a power modelling approach, different mill sizes are selected to meet the power requirements that achieve the design tonnage. In the figure below, the range of expected throughput for different ore types are plotted for a fixed grinding circuit; each ore type can process between 80% and 120% of the design throughput.

In a simple grinding circuit there will be a ball mill and a classifier. Some circuits, especially in large mills, have more units or two or three stages of grinding, but whatever is said here will apply to the complicated circuits as well as the simple ones. The two types of ball mill in general use are the grate mill and the open-end mill.

Comminution circuits are used to optimize the liberation of valuable mineral particles from waste rock for downstream separation processes. When the target grind is not achieved (under-grinding), it results in a higher number of unliberated gold particles. This in turn causes a loss in gold recovery and therefore revenue.
