Quartz: Quartz is one of the most well-known minerals on the earth with numerous uses. Sand, which is composed of tiny Quartz pebbles, is the primary ingredient for the manufacture of glass. We feel pride in introducing ourselves as a leading Quartz Lumps Exporters from India. Mineral-grade packaging is provided for safe and easy delivery of Quartz Lumps. We welcome orders from Middle East, East Asian and several other countries and ensure timely shipment. Applications : It is used as an abrasive for sandblasting, grinding glass and cutting of soft stones. Quartz powder is also used in ceramic tiles along with feldspar.

This Cast Iron slag is a by-product derived from the production of thermal insulating products. The byproduct is a ferrous slag which can be utilised in an electric arc furnace to produce crude steel. Physical Description On visual inspection, it appears to be made up of irregular shapes. Dimension: 500mm -800mm Chemical Composition Its chemical composition is homogeneous and stable with Fe contents in the range of 90 +/- 5% and P contents < 0.6% S around 0.15% and C% around 3.5%. Packing: Loose in container Loading: in 20 Container For further information, please feel free to contact us.
Quartz a crystal form of silica is found in a massive forming hill. Quartz is a mineral that's easily available from the crust of earth. And yet, it's quite valuable for its vast usage.

We are proposing about 2000tons of iron slag derived from the desulphurisation skimming process. This material is a iron by- product that is encapsulated in varying levels of contaminants (S,Mg,Si). In order to enhance its usability, the material is processed and screened. We can propose two specifications of Iron Slag - European Code: 19.12.01 - Basel Code: B1010 - HS Code: 2619.0020 - Quantity: 2000 tons currently available - Monthly quantity: 500-1000 tons depending on production - Size: 350 1200 mm - Fe content: from 77 to 86% - C content: above 2,5-3% - Bulk density: 2,8-3,4 tons/m3 - Loading type: loose in 20 (26-27 tons on average) The level of Fe% in the slag has been estimated by water displacement test.
