White N White Minerals Pvt. Ltd.

Paota, Jodhpur, Rajasthan

We are reckoned amongst the supreme Hydrated Lime manufacturers and suppliers, located in India. Synonyms which are also very commonly used in India are Salked Lime, Lime powder, Calcium hydroxide.High calcium hydrated lime Ca(OH)2 is a dry powder produced by reacting quicklime with a sufficient amount of water to satisfy the quicklime's natural affinity for moisture. The process converts CaO to Ca(OH)2. The amount of water required depends on both the subtle characteristics of the quicklime and the type of hydrating equipment available.

Limestone, also known as natural stone, raw lime stone, etc., is widely used in various industries like cement, glass, chemical, fertilizer, etc. Our excellent quality Limestone is available in mesh sizes of 100 / 150 and lump sizes of 0-6mm, 0-2mm, 0-3mm, 10-40mm, 10-100mm, and big boulders. Limestone that we provide is highly acknowledged for purity and accurate composition.

Industry wise use of Limestone

• Cement Industry
  • Limestone containing about 45% CaO and above is usually preferred for the manufacturing of cement.
  • Magnesia content in the stone should ideally be less than 3%, although as high as 5% MgO is used by the industry.
  • The proportion of Al₂O₃ + Fe₂O₃: SiO₂ should be 1:2:5. Magnesia sulphur and phosphorus are regarding as most undesirable impurities.

• Iron & Steel Industry
  • Limestone is used in this industry both in the blast furnace to lower the temperature of melting and second to from calcium silicate by combining with silica of the iron ore, which comes out as slag.
  • For this purpose good fluxing limestone low in acid constituents such as silica, alumina, sulphur and phosphorus is required. CaO +52% is preferred. The limestone should be dense, massive, preferably fine grained, compact and non-fretting on burning.

• Chemical Industry
  • The calcium carbide manufactures generally prefer lime containing 52% CaO (min.), not more than 1.5% SiO₂.

• Glass Industry
  • Glass industry required high limestone (CaCO₃: 94.5%) combine CaCO₃ and MgCO₃ should be 97.5%.

• Fertilizers Industry
  • The latest use of limestone introduced in the country is in the manufacture of calcium ammonium fertilizers, limestone is used only as carrier.
  • For this purpose limestone should contain MgCO₃ + CaCO₃ 85% (min.) SiO2 5% (max.) and acid in-soluble 14% (max.)

Specifications

• Chemical name : calcium carbonate
• Chemical formula : CaCO₃

We are reckoned amongst the supreme Calcined Dolomite manufacturers and suppliers, located in India. Synonyms which are also very commonly used in India: Burnt Dolomite, DoloLime, Calcined Dolomitic lime, steel grade dololime, steel grade dolomite.

Chemical name :  calcium magnesium oxide

Chemical formula : MgO.CaO
Burnt dolomite is a result of calcinations of natural dolomite lumps which contains 25% to 28% CaCO₃ and 15% to 18% MgCO₃. On calcination, calcium oxide contains becomes 50% to 55% and Magnesium Contains 30% to 35%.
CaCO₃ • MgCO₃ + Heat = CaO • MgO + 2CO₂
Dolomitic limestone (dolomite) has normally been formed by the replacement of some of the calcium in limestone with magnesia, a process known as dolomitisation. Theoretically dolomitic lime should be a stoichiometric mixture of CaO and MgO, i.e. 58% CaO and 42% MgO. In practice, because of impurities and differing levels of dolomitisation,  commercial products normally contain 30 - 35 % MgO .
It is the best catalyst and base chemical for steel plants.
