What WE DO ?
KS Mines is restarting a Graphite Mine with a small percentage of silver included. The mine is located in the, District Palamu, Jharkhand India, which has the one of the highest quality “flaky” Graphite in the world. The current world production of graphite is 1.3 million metric tons of which 40 percent is flaky graphite. By 2020 the increase for graphite will rise to 1.9 million metric tons of graphite and this does not include the increase for batteries or fuel cells. Most of the growth is expected in the flaky graphite which is found in India and Sri Lanka.
The known world reserves of graphite are estimated to be 800 million metric tons, which 11 million metric tons amorphous graphite reserves are in India. KS Mine is the only know mine in India to have “flaky” graphite with an estimated reserve of 1.8 million metric tons. About 59 percent of the graphite consumed is used in refractory applications, crucibles, foundry operations and steel making. Other applications for the flaky graphite include replacing silicon wafers and the expanding market of fuel cells and lithium-ion batteries. The flaky graphite is considered “the world’s next wonder material.”
The mine consists of two adjacent properties for a total of 631 acres. The first parcel is 66 acres of VIRGIN ground to be mined and the second parcel is 565 acres that have been mined since the early 1900’s. The mine was first mined for silver when India was under control of The British Government. Mr. Keyur Sinha’s Grandfather leased the mine after India gained its independence and operated the mine until his death in 1990. Now Mr. Keyur Sinha has acquired all of the ownership/lease rights of these mines.
QUARTZ, QUARTZITE & SILICA SAND
Quartz, quartzite, and silica sand are the various forms of silica. The chemical composition of silica is SiO2. These forms of silica are used in a number of industries, the important being glass, foundry, sodium silicate, silicon alloys: iron and steel, refractory and ceramic industries.
QUARTZ, QUARTZITE & SILICA SAND
Quartz is mainly used in silicon alloys and ceramic industries, though at times it is also used in the manufacture of glass. Quartzite is used in the manufacture of silica refractories and as a flux in iron and steel industry, silica sand is mostly used in the glass, sodium silicate industries and foundries.
USE CASES
GLASS INDUSTRY
The natural silica sand is the most preferred material in a glass industry, but in some cases where the glass plants are located far away from silica deposits, crushed quartz is also used. For use in glass industry the silica sand must be uniform in chemical composition, size and shape of grains.
Foundry Industry
Indian standards (IS: 3343 – 1965) specification for natural moulding sand for use in foundries.Natural moulding sand contains variable amount of clay, which acts as bond between the sand grains. This sand, therefore, posse strength, plasticity and refractoriness to varying extend depending upon the clay minerals present.
Sodium & Potassium Silicate Industry
Sodium silicate is proposed by fusing silica sand or quartz powder (20 – 100 mesh) analyzing 99% SiO2 and less than 0.25%; Al2O3, 0.03% Fe2O3, and combined CaO/MgO content of 0.05% with sodium carbonate at 1200° C to 1400° C. The ratio of Na2O3 can be varied to obtain a wide range of products.
Ferro-Silicon Industry
Quartz suitable for ferro-silicon production should have more than 98% SiO2, less than 0.4% Al2O3 and not more than 0.2% each of Fe2O3, CaO and MgO. No phosphorous or arsenic should be present in quartz. If affects reduction in the electric furnace.
Refractory Industry
Quartzite is use in the manufacture of acid silica bricks as it was high refractoriness. Refractoriness lowered by the presence of fluxes such as lime, iron oxide, magnesia and alkalies. The purity of raw material i.e., the high silica content is essential with least possible Al2O3. The presence of 0.01% Al2O3 lowers the refractoriness of silica.
Company & Norms
Complete Solution for
most difficult projects
In line with our air quality strategy and our air quality control standard, we constantly review our emissions, look for ways to improve our performance and apply controls to minimise related health or environmental impacts. We also monitor particulate gas and vapour exposure in the workplace, in line with our occupational health standards.
Each operation has its own set of water challenges and opportunities. Some are located in water-scarce environments. Others need to manage surplus water from storms or groundwater, or the quality of water we use and discharge to the environment. We work with neighbouring communities to manage the impacts we make, and look for opportunities to provide clean drinking water in countries where water is contaminated or insufficient to meet community needs.
