Abstract: White marble in Việt Nam in general,
and in Yên Bái in particular, has mineral composition, chemical composition and
whiteness meeting the requirement for use in many different industrial sectors
of the country and making them capable to participate in the world mineral
market. Yên Bái is a province having great potential in white marble, which can
be used for producing dimensional stone, facing stone, fine and superfine
calcium carbonate powder. At present, white marble is being extracted by some
companies for producing various products to be sold in domestic market and
export. With their high economic value and rather large resource potential,
these resources should be reasonably managed, extracted, processed and used
aiming to enhance the socio-economic efficiency and sustainable environmental
protection.
