Once broken into smaller pieces, the charcoal and iron ore (sand) are mixed together in a 11 ratio. 4. Charge the furnace. Before adding the iron ore and charcoal mixture, the furnace must be charged. Charging a furnace simply means heating it up to temperatures high enough for smelting to occur.
Feb 28, 2016 The flux is a mixture of several reagent chemical such as borax, silica, sodium nitrate, sodium carbonate and fluorspar. Borax is a white crystalline mineral used in glass and ceramic enamel mixes. In the smelting process, borax helps to reduce the gold smelting point of the charge and capture metallic oxides.

A mined silica sand site. Figure 4. The ravenous topography resulted from large scale open cast mining. sand falls by gravity to the bottom. After washing, the sand is then sent to a surge pile where water adhering to the sand particles infiltrates back into the ground. From the surge pile the sand is sent to the dryer and screening
Silica Sand. Silica sand, also known as silica or quartz sand, is a kind of hard, wear-resistant and chemical stable silicate mineral. Its main mineral composition is SiO2. According to different mining and processing methods, silica sand can be divided into artificial silica sand, water washed sand, scrubbed sand, selected (flotation) sand, etc.
The kind of silica sand is mainly used in the manufacture of glass, refractory materials, ferrosilicon smelting, metallurgical flux, ceramics, abrasive materials, casting, etc. It is used in construction to have a strong resistance to acid media to produce acid-resistant concrete and acid-resistant mortar.
The system is more stable and has higher smelting intensity when silicon content is around 0.41, which shows that low silica smelting practice attempt in the steel industry can lower the ...
May 30, 2018 Silica is quite similar to Borax in its gold smelting flux properties. It is selectively soluble with Gold and silver and similarly allows for the easy separation of pure metal from slag.
High purity quartz sand is used to make glass, refractories, ferrosilicon smelting, metallurgical flux, ceramics, grinding materials, casting molding quartz sand and so on. In the construction, it has strong anti acid medium erosion ability to make acid resistant concrete and acid resistant mortar.
User of Silica Sand are spread over a very wide range of industry where functional roles of it are also varied, like Silica Sand is used as a filler in porcelain, ceramics, sanitary ware and Engineered stone industry while Silica Sand are used a lining refractories in induction furnaces, as a
15.2.2 Chromite Sand. Chromite is a widely used aggregate valued for its relatively low thermal expansion and good chilling power, particularly for steel castings. However, the general problem with chromite is only found in steel casting operations where it is commonly employed as a facing sand for silica moulds.
