(Chem.), Baikal Minerals Group, Deputy Director General; Irina KULESHOVA, laboratory head, ОАО R.&D Firm Spektr Lakokraska (Paintwork Spectrum) Broadening the raw materials base is still in the mainstream here in this country.

The consumer qualities of our domestic raws, too, still leave much to be desired. Mineral fillers are an essential part of paintwork products.

In fact, our country is rich in minerals that could be utilized as pigment extenders. But only a few have been selected thus far. East Siberia (Irkutsk oblast and Buryatia) holds out the best promise. True, it lies far from potential consumers; however, deposits are situated near the Trans-Siberian trunk railroad, and they are quite competitive, since the quality of local ores allows to do without flotation (dressing and separation) and further beneficiation.

Located in the Northwest (Karelia and Kola peninsula) are Kovdor (phlogopite, amber mica) and Chupa (muscovi ... Читать далее
