The global demand for indium ore is increasing at a rate of 30% every year, which is a new strategic resource that countries all over the world compete for fiercely. After the Nandan mine disaster in Guangxi, Nandan mine was closed and the largest indium mine resource in China was preserved.

Two thirds of indium resources in China are concentrated in Guangxi. The highest price of indium ore exceeds 6,543,800 yuan per ton. This has caused many small refineries to flock, and the amount of indium mining has soared, but the price has plummeted. At present, the price per ton is only 3.8 million yuan. Tan Yongren, general manager of Guangxi Nandan Ji Lang Indium Industry Company, said: "This price is close to the cost, and many indium factories do not produce it."
