In the Indo-China region, Vietnam is rich in mineral resources relative to Laos and Cambodia. So far, more than 60 kinds of minerals have been discovered, mainly energy and non-metallic minerals. Graphite, kaolin, apatite, precious stones and various building materials and minerals are found in non-metallic mines. According to the existing reserves of 8 kinds of non-metallic minerals, the reserves of phosphate rock are the largest with reserves of apatite and phosphate rock of 1.699 billion tons and 6.9 million tons respectively, followed by 1.57-167 million tons of kaolin, 53.09 million tons of silica sand and 2787 Ten thousand tons of pyrophyllite and feldspar were 500 million t, alum stone 1.4 million t, silage 160,000 t.
