Pb Zn ore divides into sulfide Pb Zn ore and oxide Pb Zn ore . Flotation is the most widely used in separating sulfide Pb Zn ore , to separate zinc and plumbum , sometimes for separating sulfide iron and other minerals . Sulfide Pb Zn ore process divides into priority flotation process , mix separating flotation , asynchronous flotation ,and so on .It is a high technological enterprise
By the 11th century, stamp mills were in widespread use throughout the medieval Islamic world, from Islamic Spain and North Africa in the west to Central Asia in the east. A later example was the Cornish stamps , consisting of a series of iron hammers mounted in a vertical frame, raised by cams on the shaft of a waterwheel and falling onto the ...

2. Ore Dressing Technology and Equipment. The selection of sand and gold mine is mainly based on the physical properties of minerals, such as grain size, shape and specific gravity, so as to achieve the purpose of sorting in the moving medium flow. This is the oldest method of selection in Mineral Engineering Gravity concentration method.
The solubility of gold in a water and cyanide solution was discovered in 1783 by Carl Wilhelm Scheele, but it was not until the late 19th century, that an industrial process was developed.The expansion of gold mining in the Rand of South Africa began to slow down in the 1880s, as the new deposits being found tended to be pyritic ore.The gold could not be extracted from this

Copper dressing relied extensively on manual labour throughout the 18th and 19th centuries, though mechanisation did play a part. Copper crushers were introduced in the early 19th century and low grade or otherwise difficult ores were also stamped at some mines. Copper ore was spalled in the same way as with tin.
Gold gravity separation makes use of gravity forces of materials with different density and difference of mineral granules to enrich gold from the ore. Gravity separation is widely used in gold enrichment for both placer gold ore and rock gold ore. Gravity separation can separate gold from the impurities because there is a big density difference between gold and impurities.
