Lead ore can be lead sulfide ore and lead oxide ore with the different distribution in the ore. Lead sulfide ore is commonly known as galena, which is mostly in the state of coarse grained disseminated in lead ore. While the lead oxide ores are mostly exist in fine condition. So they need different lead jigging plant to process.

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.

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.

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.
