ways to process ores

  • Reprocessing

    Compressed ores require 1 unit to process, while uncompressed ores require 100 units. You cannot process uncompressed ores with less than 100 units of a single type, e.g. 75 units of Veldspar cannot be combined with 25 units of Dense Veldspar for processing. Both compressed and uncompressed ores yield the same amount of minerals per batch.

  • Uranium: How is it Mined?

    Uranium resources can be extracted from the ground in three ways: open pit, underground, and in-situ leach (ISL). Open Pit Mining. Open pit mining, also known as strip mining, is the removal of surficial soils and uneconomic rock to get at the ore below. Ore grades are normally less than 0.5%.

  • Extracting a metal from its ore

    that contain sufficient metal to be of practical and economic use are called ores. Metals are usually extracted from ores using a combination of heating and reduction with carbon in the form of charcoal or coke. Not all metals can be extracted from their ores in this manner and may need to be extracted by a process called electrolysis.

  • Introduction to Mineral Processing

    Introduction to Mineral Processing. The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.

  • Copper Ore Types: Sulfides vs. Oxides

    Copper ore types: Oxides. The copper sulfate solution (called the pregnant leach solution) is then stripped of copper via a solvent extraction and electrowinning (SX-EW) process. Alternatively, the copper can be precipitated out of the pregnant leach solution through a process called cementation, whereby the copper is contacted with scrap iron.

  • Extraction of Metals: Ores and Minerals

    The process of extracting metal ores buried deep underground is called Mining. The metal ores are found in the earth's crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges.
