  • Earth Science for Stem

    Mineral processing is the process of extracting minerals from the ore, refining them, and preparing these minerals for use. The primary steps involved in processing minerals include: 1. Sampling – is the removal of a portion which represents a whole needed for the analysis of this material. 2. Analysis – is important to evaluate the valuable component in an ore. This includes chemical ...

  • What is Mineral Processing? (with pictures)

    Early mineral processing typically involved manual labor, such as striking ore with hammers to break it open. This process of separating minerals from ore by hand was known as spalling. Similar processes were developed during the 10th century that mechanized the use of hammers to break the ore. These stamp mills typically used a water wheel to lift the hammers and the force of gravity to draw ...
