我国的菱镁矿及其制品市场需求预计在未来几年里将有较大发展。1991年，我国钢铁工业消耗菱镁矿制镁砂量约为明万t，其他工业部门消费需求为30万t，轻烧镁消耗量为24万t、镁砂与轻烧镁消费量需求合计为134万t。若按每吨镁砂（含轻烧镁）折矿石约2．3t计，共需菱镁矿308．2万t，
Demand for magnesite and its products in China is expected to grow significantly in the coming years. In 1991, the volume of magnesia consumed by the iron and steel industry in China’s steel industry was about Million tons, the consumption demand of other industrial sectors was 300,000 tons, the consumption of light-burned magnesia was 240,000 tons, and the consumption demand of magnesia and light-burned magnesia was the total 1.34 million t. If per ton of magnesia (including light-burned magnesium) off about 2.3t dollars, a total of 3.082 million tons of magnesite,
