Mineral Processing and Ore Dressing - 911 Metallurgist

02/06/2016  Before the event of ore dressing, crude ores were shipped directly to the smelters, or the refineries, with the shipper paying the freight and treatment charges. These charges varied with the type of ore and the distance from the smelter. In all cases they were many times our modem milling costs. While the smelter recovered the principal values, substantial losses of other metals and even ...

Ore Dressing - Sympatec

The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation. Furthermore, flotation cells are sensitive to solid overloading. Another relevant process parameter is therefore the solid concentration of the ore suspensions fed to the flotation cells.

Flotation ore dressing Britannica

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.

Out of Oblivion: A landscape through time

The earlier methods of dressing occurred near to the shafts and involved manual processing and left few visible remains other than small mounds of gravel-like rock, often vegetation free because of the heavy metal content of the waste material. Later, large centralised dressing floors were built. These mechanised dressing floors were equipped with water-powered ore crushers, and hotching tubs ...

Derbyshire lead mining history - Wikipedia

Dressing was the process of extracting the ore from the rock in which it was embedded and washing it, a further refining process. In the days of bole smelting the ore was roughly washed clean of waste minerals and dirt before being riddled for bing ore. The ore for the new smelters was smashed, or crushed, into pieces about the size of peas. This was done by hand, using a hammer called a
