  • Solution Mining an overview ScienceDirect Topics

    There are four distinct methods used to mine the Wyoming Trona ore: (1) solution mining, (2) room-and-pillar mining, (3) longwall mining, and (4) shortwall mining. In the solution mining process, dilute sodium hydroxide (NaOH) is injected into the Trona to dissolve it.

  • Extracting Lead Materials from Ore

    Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multi-step process. First the lead ore is ground into small particles that are less than 0.1mm, giving the ore a texture similar to table salt. Next the lead powder is put through a flotation

    Other commercially significant lead-containing minerals are cerussite (lead carbonate) and anglesite (lead sulfate). These are known as secondary minerals in that they derive from galena through natural actions, such as weathering. Cerussite, for instance, is formed by the action of carbonate groundwater on galena, whereas anglesite is formed when galena is subjected to sulfate solutions generated from the
