Zircon sand is generally found in land of ancient coastlines,some of which can be found very far inland,where the heavier mineral sands formed hardened deposits.These deposits are typically mined via dry or wet(dredge)mining techniques.

South Africa chromite sand casting South Africa chromite sand casting , Originally from South Africa ,is a special kind of sand for casting , chromite sand casting is a natural spinel mainly composed of chromite , Chromite sand casting used as a highly fireproof sharpener for moulds and cores. Purpose 1 foundry industry Its properties enable the material to be used in high duty grey iron and steel foundries as core and mould making sand. 2 steel industry In steel production, Chromite Sand Casting is used as well filler for protection of the sliding gate in large steel holding ladles. 3 glass industry When ground to a fine flour, Chromite Sand casting is used for the production of green glass beverage containers
The process of shell type steel filling (dry sand) is to put the shell type into the barrel and fill the steel balls (dry sand) around the barrel to reinforce the shell A casting process in which a mold is formed and a molten iron is cast. Castings are cooled by steel pellets, the faster the cooling speed, the better the air permeability, the better the recovery of steel pellets, the smaller the equipment investment, the slower the die consumption, and the easier the mold change.
Ashapura's naturally occurring limestones are endowed with high purity and optical properties; these are particularly suitable for applications such as paint, polymer and paper applications. Limestone is finely ground to achieve superior application benefits in polymer and paint formulations. Limestone with highest whiteness and brightness with minimum impurities is exclusive characteristics of Ashapura limestone deposits.

Step1: chrome ore raw material is processed by water washing. Step2, drying raw materials to remove water; Step3, drying raw materials into the vibrating screen, screening out the size of the customer needs; Step4, the size of the sieve for magnetic separation, the purpose of iron and silicon removal. After magnetic separation, the chromium content reached more than 46% and the silicon content was less than 1%. Step5: package the finished product.
Foundry chromite sand is a natural process products of chromite through the broken screen classification, chrome ore, its main chemical composition of cr2o3, this kind of sand heated volume stability, high thermal conductivity, when in contact information with the molten metal, not only has good resistance to basic slag, not with ferric oxide and other chemical reactions, and itself has the characteristics of the solid phase sintering, can be a very good prevent the infiltration of molten metal, avoid to touch sand defects, suitable for all kinds of stainless steel, alloy steel and carbon steel gradually shape the original sand core and coating.
Chromite ore, also known as chromite ore, is a special sand for casting, is a natural spinel based on chromite, after crushing, grinding, screening into a specified size, suitable for molding (core) sand.
Garnet sand is made of garnet as raw material. It is a kind of iron-aluminum silicate with moderate hardness, high melting point and stable chemical properties. According to different products and structures, it presents different colors, such as dark red, brown red, pink and black. Widely used in optical industry, electronic industry, machinery industry, oil and gas and other industries.

Decolorizing sand, is also called oil decolorized sand and can replace decolorizing clay to deal with different oil industry. It has good fluidity and function of deacidification, deodorization, decolorization and adsorption and filtration media. It is used in the final refining process in the diesel production process (used in the outflow of diesel). A certain proportion of black diesel oil is light yellow transparent after being adsorbed and purified by filter sand (decolorized sand).
