Waste copper slag is a refractory material with high iron content, but it is difficult to recovery iron minerals from the slag because the iron mainly occurs in fayalite.

The most popular garnet sand right now is river garnet sand, which is more clean than rock garnet sand. China garnet sand includes rock garnet sand and alluvial garnet sand. Rock garnet sand has a little higher hardness than river garnet sand. So we can say, the river garnet sand is suitable for wat

In July 2018, RMPI (Raw Materials Price Index) stands at 237.83, down by 2.74% compared with the previous month; up by 36.53% compared with the same period of 2017. The price of bauxite remains stable, with continuing shortage of ore supply; fluctuation situation of magnesia lasts for nearly 1 year,

Brown fused alumina is a kind of artificial corundum produced by high temperature smelting of natural bauxite. Although the main component is Aluminium Oxide, it still contains a lot of other chemical components such as silica, iron oxide, titanium oxide, etc.

Oil and Gas Generating ConditionsGeneralized oil is found in the ground or cracks in the pores of the rock is given priority to with liquid hydrocarbon and gaseous hydrocarbon combustible organic minerals. Also known as crude oil, liquid petroleum gas hydrocarbon is often referred to as natural gas.

While the oil and natural gas industry has had its ups and downs, many speculate it is again poised for growth due to the current political climate.

Corundum has many colors as it contains different pigment particles. According to the color of corundum, it can be divided into Brown fused alumina, white fused alumina, black fused alumina, etc. They are all belong to artificial abrasives and widely used for abrasive industry.

SEPPE produces oil fracturing proppant which is the best quality materials. Then how to recognize high quality oil fracturing proppant?

Proppants used should be permeable or permittive to gas under high pressures; the interstitial space between particles should be sufficiently large, yet have the mechanical strength to withstand closure stresses to hold fractures open after the fracturing pressure is withdrawn.

Referred to as refractory brick. Refractory material with a certain shape and size. According to the preparation process, it can be divided into bricks, brick, electric melting brick (Cast Brick), the refractory insulating bricks; according to the shape and size, it can be divided into standard brick, ordinary brick, specific rotation.
