We specialize in the design, detailed engineering, supply, erection and commissioning of mineral beneficiation plants for the following: -

We have already designed a low-grade rock phosphate beneficiation plant and commissioned it in India. This is the first plant set up in the private sector, which has been working successfully.

We have a team of experts in evaluation of ore characteristics and development of basic engineering for setting up beneficiation plants for the metallic and non-metallic ores.

Images of Mineral Benefication Plant
We undertake development and erection of Mineral Benefication Plant on turnkey basis and also execute production & maintenance contract for these plants.

The Sulfuric Acid, Rock phosphate Mineral Powder and water are mixed in a agitated process vessel connected with scrubber system. The above slurry solution is filtered and the filterate is Collected in another agitated process vessel as Crude Phosphoric Acid for further processing. The solid part is Gypsum, which is thoroughly washed with water to make it free from Crude Phosphoric Acid. The wash water \ recycled water containing phosphoric Acid is recycled in next batch with Rock phosphate and Sulphuric Acid. During this step the impurities of Rock Phosphate Mineral [such as Florspar CaF2, CaCo3 Lime stone] are reacted with Sulphuric Acid. The CaF2 forms HF with sulphuric Acid. The HF is reacted with Silica to forms SiF4 is highly soluble in water to form H2SiF6 and silica inside the Scrubber as well as inside the agitated Process vessel. This Acid is concentrated and the concern condensate in neutralised with Ca(OH)2 & insoluble precipitate is mixed with hyproduct Gypsum. The Crude Phosphoruc Acid contains further some H2SiF6 The H2SiF6 [Hydro Silicic acid or Hexa Fluoro Silicaste] is mixed with Lime stone Powder to form insoluble Florspar (CaF2), which is soluble only in strong concentrate acid. This is also filtered with partial precipitate of Calcium Phosphate (Tri) this insoluble is recycled with Acid recovery of P2O5 in Adulation process with Rock Phosphate. After filtering above Slurry Solution, the filterate is Purified Phosphoric Acid.

The Purified Phosphoric Acid is neutralized with Hydrated Lime solution up to required 5.5 pH for Di, to precipitate water insoluble Calcium Phosphate. Then the above slurry solution is filtered and washed with raw water. The wet cake precipitate is Di Calcium Phosphate Then liquid is untreated liquid effluent, which is collected in neutralization tank. After adding Ca(OH)2 upto pH 8.5 and airing for proper mixing then only solution is filtered. The insoluble cake Di Calcium Phosphate. The wet cake of DCP is dried, then blended for uniform batch, Then sieved, then tested, packed and stored for sale.
