• How do we extract minerals?

    Placer mining is used to recover valuable minerals from sediments in presentday river channels, beach sands, or ancient stream deposits. More than half of the world's titanium comes from placer mining of beach dunes and sands. In placer operations, the mined material is washed and sluiced to concentrate the heavier minerals.

  • Infographic: The Mineral Exploration Roadmap

     · In this stage, boots are now on the ground – and it's time to explore the backwoods for showings. Prospectors will stake claims, map outcrops and showings, and search for indior minerals. The goal of the prospecting stage is to find the earliest piece of the exploration puzzle: the clue that there is something much bigger beneath. 3 ...

  • Mineral Exploration, how it's done

    Mineral exploration is the process of searching for evidence of any mineralisation hosted in the surrounding rocks. The general principle works by extracting pieces of geological information from several places, and extrapolating this over the larger area to develop a geological picture. Exploration works in stages of increasing sophistiion, with cheap, cruder methods implemented at the ...

  • Particle Analysis in Mining and Minerals

    Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.
