Overview

About Dolomite

Dolomite is a carbonate mineral that carries magnesium alongside calcium — the reason it is asked for where limestone alone will not do. Steelmakers use it as a flux and to protect refractory linings, glassmakers as a source of both oxides, builders as aggregate and filler, and farmers, where the soil calls for it, to correct acidity and add magnesium.

Deshwali Minerals supplies dolomite graded to the size or mesh the buyer's process needs. The composition and size fractions on offer are confirmed by the company against the test certificate for the consignment, so the figures you plan on are the figures that arrive.

Applications

Where Dolomite is used

The duty determines the grade. These are the applications this product is technically suited to.

  • 01Flux and refractory protection in steel and ferro-alloy making
  • 02Glass manufacture, as a source of calcium and magnesium oxide
  • 03Construction — aggregate, filler and building products
  • 04Agricultural liming and magnesium correction, where the soil calls for it
Selection

Choosing the right dolomite for the duty

The grade, the size fraction and the packing follow from how the material will be used. These are the points the sales desk settles with you before quoting.

  1. 01

    The duty

    A flux, a reagent for pH correction, a stabiliser under a road or a binder in mortar each weigh the parameters differently: reactivity for a melt shop, particle size for a dosing plant.

  2. 02

    What your intake takes

    Lump sizes for a kiln or furnace charge; a ground powder or hydrated lime for a feeder, slurry tank or silo. The size fraction is screened to the system it feeds.

  3. 03

    The parameters that matter

    Agree the specification lines that decide fitness — CaO or available lime, MgO and silica limits, reactivity, moisture, sieve size — and the test method for each, so the certificate answers the right question.

  4. 04

    The journey and the storage

    Packing is chosen against transit distance, the season and what will unload and store the material at the destination.

  5. 05

    Quantity and schedule

    A one-off lot and a monthly contract are produced and priced differently. Consignments start at the minimum order and are scheduled around confirmed dates.

Handling

Packing, storage and transport

Lime degrades on contact with moisture and air. How it is packed and stored is a technical decision, not a cosmetic one.

Packing

  • Packing agreed at order

Recommended against transit distance and destination conditions.

Storage

  • Stockpile in a bunded, drained area; keep ground material bagged and dry.
  • Segregate size fractions to preserve grading.

Transport

  • Bulk tipper and jumbo bag despatch from Borunda, Jodhpur.
  • Containerised loading available for export consignments.

Safety

  • Low hazard in bulk form; control airborne dust during handling and transfer.
  • Refer to the Safety Data Sheet before handling. Request the SDS
