Ironsand, also known as iron-sand or iron sand, is a type of sand with heavy concentrations of iron.It is typically dark grey or blackish in colour. It is composed mainly of magnetite, Fe 3 O 4, and also contains small amounts of titanium, silica, manganese, calcium and vanadium.. Ironsand has a tendency to heat up in direct sunlight, causing temperatures high enough to cause minor burns.
15/01/2013· direct smelting is a viable option both in the laboratory and in field trials. By using the right combination of borax, soda ash and silica, gold bearing black sands were smelted with relatively high recoveries. Field tests for recovery via amalgamation, heating and smelting gave an average recovery of about 88% while figures for direct

It is therefore often used as a foundry sand. With a melting temperature higher than most metals, it can be used for the molds and cores of common foundry work. Refractory bricks are often made of quartz sand because of its high heat resistance. Quartz sand is also used as a flux in the smelting of metals.
I am currently using Borax, Silica flour, Soda ash and Potassium nitrate, the sludge contains also copper, I need a guideline on flux calculation to use in order to move the copper or any other Base metal to the slag. I would like to know more about flux calculation for gold smelting. I use Borax, Silica flour, Soda ash and Potassium nitrate
Silica (silicon dioxide, SiO 2) occurs as the mineral quartz, a major constituent in many igneous and sedimentary rocks, and the most common detrital mineral in sandstone.As a commodity, the term silica is applied to quartz in all its forms — as vein or reef quartz, quartz pebbles, sandstone, quartzite, or as unconsolidated sand.
The present invention provides a method for smelting silicon carbide and its equipment. It is characterized by that its smelting furnace is electric resistance furnace, and its reaction material includes carbon material and silicon dioxide material, after the reaction materials are mixed, they are placed along the periphery of furnace core, said surface core is formed from graphite powder.
