The SiO 2 content is also high, and the A/S is low, generally 4-6. The amount of rich ore is small and scattered. Berlin Packaging (Qingdao) Co.,Ltd , https://www.berlinpackaging.cn
China is also rich in nepheline resources. In the old areas of Yunnan Province alone, the initial survey shows that the reserves amount to 3 billion tons, of which C 1 +C 2 is 280 million tons, and the grade is A1 2 O 3 24, K 2 O8%-10%, which is characterized by a high K. There are also nepheline resources found in Sichuan Province.
China also has abundant alum resources. There are reserves in Lushan, Pingyang, Zhejiang Province: A+B+C 1 +C 2 grade 140 million tons, alumite content 46.31%; outside surface 104 million tons, alumite content 32%. Reserves in Lujiang, Anhui Province: Table: B+C 1 +C 2 level 130 million tons, alumite content 38.7%; table rich ore 0.6 million tons, alumite content 47.5%.
