Predominant minerals in the oxide ore zone are oxidized minerals of lead and zinc (descloizite, cerussite, willemite, smithsonite) with a minor amount of sulfides, while the sulfide ore zone contains sulfide minerals (galena and sphalerite) predominantly. As main gangue minerals, calcite, dolomite, and some silicates are present in both ore types. Before 1960, the lead-vanadate-containing ore

The lead, zinc and copper veins on Mendip were deposited by hot mineralising fluids (typically between 50 and 150° C) rising up from depth and depositing various minerals as they cooled. The source of the fluids were the deep sedimentary basins either side of the Mendips. As the Triassic and Jurassic sediments in these basins were buried, compacted and heated over time, some of the water in

A major and primary Lead mineral is galena (chemical formula = PbS) which comprises of 86.6% of Lead [1]. In order to smelt this mineral, a blast furnace is needed to be used. A blast furnace is an enormous oven which is used to accomplish the smelting processes [2]. The process in which galena is smelted requires two important chemical reactions to occur within the furnace. 1) The galena is

History of Lead mining in the Peak District and Derbyshire
In geological times mineral-rich magma was intruded into fissures and faults in the limestone. It cooled and crystallised, leaving deposits of galena (lead sulphide) surrounded by crystals of fluorspar (calcium fluoride) and calcite (calcium carbonate). Sometimes barytes (a barium ore) was found with the lead while in a few areas such as Mixton and Ecton the deposits were primarily copper

Mining in Roman Britain
The process of extraction, cupellation, was fairly simple.First, the ore was smelted until the lead, which contained the silver, separated from the rock. The lead was removed, and further heated up to 1100° Celsius using hand bellows.At this point, the silver was separated from the lead (the lead, in the form of litharge, was either blown off the molten surface or absorbed into bone ash
