The government of Fujairah has granted the company a total lease area of 110.8 Hectares over which 2600 meters of core drilling activity has been carried out and a total mine-able reserve of 380 Million Metric Tons high grade, low silica Limestone has been
Intervals of high-calcium limestone are present in the low-silica zones. These deposits are potentially suitable for use as rock dust in underground coal mines and as neutralizing agents in surface-mine reclamation and acid-drainage control. The intervals of chemically pure stone in Harlan County may be sufficiently thick to produce by
Low Silica Limestone (+95% CaCO 3, Low Silica < 1.5%) Low Silica Limestone is used in steel plants with BOF technology as a flux. Chemical Grade Limestone (+94% CaCO 3, Low Silica < 2.5%)Chemical grade limestone is used mainly in chemical industries producing quick lime and hydrated lime.
Sep 12, 2019 The Newman Limestone crops out along the Pine Mountain Thrust Fault in southeastern Kentucky, and several mines have been opened to provide high-calcium stone for the rapidly growing area. High-calcium, low-silica stone occurs in the Newman and can be used as rock dust for explosion abatement and for acid mine-drainage control.
These mines are around 10 KM from Gotan. The limestone deposit of Sawai-Heera & Sona mines of Basni lease are considered to be the best available deposit in the entire Sojat-Bilara-Nagaur belt. The deposit contains very low silica, high calcium and moderate decrepitation index.
Limestone The production of limestone in 2016-17 at 313.2 million tonnes increased by about 2% as compared to that of the previous year. There were 771 reporting mines in 2016-17 as against 807 during the previous year . Twenty seven mines each producing more than 3 million tonnes per annum contributed 42% of the total production of limestone

For example, if the water body was stormy or muddy poorer quality limestone or shales exist today at that location. If the water body was calm there is less likelihood for contamination and as a result high quality stone exist in present form. The Kentner Creek operation mines Silurian age limestone that was deposited in a unique environment.

At Caroline, the limestone is exceptionally white, contains a significant silt-sized and finer carbonate fraction and is low in deleterious non-carbonate materials such as sand, silt, clay, dolomite, flint, iron and manganese. The depth to water table is ~8 m, and overburden comprises approximately 1 m of soil and discoloured limestone.

Tandur Grey Limestone Tandur Grey Limestone is a common raw material used in glassmaking, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber. Quality We have an immensely dedicated management team with vast experience coupled with tremendous technological expertise constantly helps us in produce Quality Products.
Wollastonite is a calcium inosilicate mineral (Ca Si O 3) that may contain small amounts of iron, magnesium, and manganese substituting for calcium. It is usually white. It forms when impure limestone or dolomite is subjected to high temperature and pressure, which sometimes occurs in the presence of silica-bearing fluids as in skarns or in contact with metamorphic rocks.
mines in 2014-15 as against 60 in previous year . About 51% of total production was contributed by 15 principal producers. About 20% production of dolomite was reported as an associated mineral with asbestos, barytes, clay (others), iron ore, limestone, magnesite, shale and steatite. Three mines producing more than 2 lakh tonnes annually

We supply low silica limestone sourced from U.A.E and Oman which are widely used in steel and cement industries. We can also supply high calorific value coal from Indonesia for various power plants. We ensure good quality of both the minerals and are interested to get inquiries from serious buyers.
May 01, 2020 Low grade dumped limestone sample having high silica of 8.1%, 36.8% CaO, and 3% Al 2 O 3 has been studied with the aim to reduce the silica level to below 3% for its utilization in iron making. Beneficiation study of the sample was initiated with des of the feed sample of −100 µm to remove the siliceous ultrafine particles and to improve the feed quality.

SILICA SAND. Silica sand or quartz sand: Quartz particles (SiO2) with a size between 2.00 and 1.05 mm, formed as a result of disintegration of magmatic metamorphic rocks rich in quartz. Quartz sand is white, while sands containing iron oxides have colors that range from pink to red or brown.

The State is enriched with steel grade, refractory grade and low silica dolomite. 1152.66 million tonnes of dolomite deposits are spread over in the districts of Balaghat, Chhatarpur, Sagar, Mandla, Jabalpur, Katni, Sidhi, Narshinghpur, Seoni, Jhabua, Khandwa and Dewas.
The deposits of low-silica and high-calcium stone are thickest in the southwestern part of Letcher County and commonly thin northeastward. The thicker deposits of chemically pure limestone and dolomite may be an economically exploitable source of rock dust for underground coal mines, and a source of stone for surface-mine reclamation and acid
