Recently, the "7N high-purity arsenic clean and efficient preparation key technology and large-scale complete set equipment development and industrialization project" was formally put into pilot operation, marking start of trial production of Humon Smelting's high-purity new material development and industrialization project.

With a total investment of RMB340 million (USD50.67 million), the project entered the construction stage in March 2020 based on "making on plan and constructing in stages". In addition to high-purity arsenic, the project will also produce high-purity antimony, high-purity bismuth, high-purity tellurium and other high-end materials. After going into commercial production, the project will have an annual production capacity of 50t of high-purity arsenic, 50t of high-purity antimony, 50t of high-purity bismuth and 50t of high-purity tellurium.
