  • Mitigating Environmental Hazards of Sand Processing

    The use of wet processing technology for sand production is an established process across the world. It allows one to increase the efficiency of concrete production by giving a sand product with greatly reduced volumes of material in the minus 74 micron range. When considering the sand fraction, the wet process is required for a number of reasons:

  • What is Industrial Sand? National Industrial Sand

    Silica sand deposits are most commonly surface-mined in open pit operations, but dredging and underground mining are also employed. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities. It is then dried and sized to produce the optimum particle size distribution for the intended application.
