Dolomite occur mainly in Mahabharat range in Dhankuta, Khotang, Udayapur, Sindhuli, Dolakha, Kavre, Kathmandu, Makwanpur, Dhadhing, Syangja, Palpa, Baglung, Gulmi, Arghakhanchi, Dang, Pyuthan, Sallyan, Rolpa, Rukum, Jajarkot, Surkhet, Dailekh, Jumla, Achham, Doti, Bajhang, Bajura, Baitadi and Darchula districts in the Lesser Himalaya and in some parts of Higher Himalaya and Tibetan Tethys (Inner Himalaya) region (Kaphle, 2005, 2020).
The quality of dolomite depends on its chemical
composition like MgO%, CaO%, SiO2%, Al2O3%, Fe20%, LOI%. Depending on these
oxides it can be used in different industries. Dolomite is a potential source
of metallic magnesium. It is used to manufacture soral cement and also in
refractories, high magnesium lime, flux for iron and steel industries,
ferroalloy industries, fertilizer industries and acid water treatment plants.
Dolomite can be directly used in agricultural field to neutralize acidity and
also to make up the loss of magnesia in soil. MgCO3 is used on a small scale as
filler in the paper, paint, rubber, varnish and pharmaceutical industries. In
huge amount it is used as building/ construction stone, aggregate for concrete,
road fillings and asphalting materials.
