antimony ore mining machinery in the republic of Congo

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. Mining, oil and gas studies include all operations involved in the exploration, evaluation and extraction of minerals, metals, petroleum and fossil fuels from earth. Mining engineers investigate mineral resources and are responsible for planning and supervising the construction of mines.
