Here are the main steps in processing diamond ore. A number of these processes use equipment from Multotec: 1- Crushing. The first step in kimberlite ore processing is crushing. This process reduces large run-of-mine lumps into smaller pieces, making them easier to handle, and releases or liberates the diamonds to be recovered in subsequent steps.

The primary ore is galena or Lead sulphite PbS. This is unstable, and on prolonged exposure to the atmosphere it oxidizes into the minerals cerussite PbCO3 and anglesite PbSO4. Lead ores are usually associated with other metals, particularly silver which can be mined at the same time – and zinc, which can cause problems during smelting.

1.1. Galena Ore Characterization Several studies on the characterization of galena ore have been carried out in the recent past. Some of the reported results on the composition of galena from dif-ferent parts of the world are summarized in Table 1. Galena is composed of lead as a dominant metal followed by sulphur, iron and zinc in that order.

Galena is by far the greatest ore of lead. Galena is the most common mineral containing lead, and contains mostly lead. Since the extraction process is so simple, lead has been extracted from Galena since the earliest times. To quote Allen N Wollscheidt, "Galena, back 75 years ago, was the stuff -- the crystal -- of crystal radio sets.
