  • Process for extracting gold, silver, platinum, lead,

    A process for extracting metals having lead affinity from mineral ores. The process is in steps including, pulverizing the ore material, drying the ore, melting elemental lead in a melting chamber and maintaining the molten lead within a preselected temperature range, introducing the ore into the lower portion of the melting chamber, agitating the molten mixture, transferring the molten

  • Metals and their ores complete list - Day Today Gk

    26.04.2018· The most common metal ores are oxides and sulphides. 3. Sulphides are the oldest ores, formed in the Earth's history when there was a lot of sulphur from volcanic activity. 4. Oxides formed later when photosynthesis in plants released large amounts of oxygen into the atmosphere. 5. Iron ore is the most common element in the world and makes up close to 5% of the Earth's crust. This makes it

  • Copper Mining and Extraction Sulfide Ores

    Metals are often found as compounds in ores. An ore is a rock or mineral that has enough metal in it to make it worth extracting. Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These

  • Reduction of Metals (Extraction from Ore) - A

    There are 3 main methods of extracting metals from their ore. They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal. Extraction using carbon. Metals such as zinc, iron and copper are present in ores as their oxides. Each of these oxides is heated with carbon to obtain the metal. The metal oxide loses oxygen

  • Ore sorting: Efficiently optimise the treatment of

    Use ore sorting equipment to concentrate ores and cut process costs There are many ways of improving recovery processes for a wide variety of ores using sorting equipment. At STEINERT we always take the same approach: sorting waste rock and ore with low concentrations out from the process at an early stage to save energy and resources and to unlock more enriched ore more effectively.

  • Ore sorting: Efficiently optimise the treatment of

    By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations. The entire processing line can be planned in semi-mobile form and consists only of crushers, screens, belts and sorting machines. This allows immense cost savings for transport, since the waste rock is disposed of on-site. Additionally, higher prices can be achieved with the concentrate since the ore

  • Metal ore mining in Europe - Mineral Processing

    Import requirements for metal ore concentrates have risen sharply in the EU. In the case of copper, imports of copper ore concentrate amounted to 4.25 million tonnes per year (Mta), according to figures from Eurostat alone. Three quarters of the imports were covered by Chile (26 %), Peru (23 %), Brazil (11 %), Argentina (9 %) and Canada (6 %). For other metals, the ratios between extraction

  • Concentration of Ores: Hydraulic Washing, Froth

    An ore of a metal is an impure source, this means other than the metal it consists of many other impurities such as sand, grit, clay, rocks etc. These impurities are collectively known as gangue. Gangue is generally commercial valueless and we must separate it from the ore. This entire process is the concentration of ores or even dressing or benefaction.

  • Hydrometallurgy - Wikipedia

    The primary types of metal recovery processes are electrolysis, gaseous reduction, and precipitation. For example, a major target of hydrometallurgy is copper, which is conveniently obtained by electrolysis. Cu 2+ ions reduce at mild potentials, leaving behind other contaminating metals such as Fe 2+ and Zn 2+ .
