This process utilizes magnetic and float separation to remove impurities. After the sand has been washed and dried and contaminants have been removed, it is screened. In this process, sand is separated according to grain size and stockpiled for future blending. These numerous demands for sand require mining of our dunes and other sand resources. Our main products include crushing equipment, sand making equipment, beneficiation equipment, grinding equipment and building materials equipment, welcome to purchase;

Placer mining is used to recover valuable minerals from sediments in present-day 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.
Sand is also the most consumed substance after water, being used in virtually every construction or manufacturing process, even used as an ingredient in toothpaste.

Before mining for frack sand, operators must remove “overburden” – topsoil or subsoil overtop the sand that is mainly composed of clay, silt, loam, or combinations of the three. Removing the overburden requires scrapers or tracked excavators. After removal, the operator stockpiles the material in man-made earth mounds called berms.
Oil sand is a mixture of bitumen, sand and water. Because it does not flow like conventional crude oil, it must be mined or heated underground before it can be processed. Our oil sands business recovers bitumen through surface mining and steam injection technologies and upgrades it into refinery-ready crude oil products.
