Allow the action of the nitric acid to cease before adding more.

The complex As-Au-Sb ore is also an important antimony resource that is predominantly mined in Hunan and other places in China. It is essential to develop an economical and environmentally friendly process for the extraction of antimony from this ore. Antimony production involves hydrometallurgy and pyrometallurgy, the latter being still dominant.
