実験手順

In the process of the invention, the arsenic-containing gold ore is treated with Caro's acid, i.e. peroxymonosulphuric acid (H2SO5), to oxidize the arsenic sulfide in the ore to the water soluble arsenate form. Caro's acid is produced by reaction between 92 to 99% sulphuric acid and 50 to 75% aqueous hydrogen peroxide in a mole ratio of 1.5:1 to 3.5:1. The acid may be diluted with water for use in this invention, and usually has a concentration in the range of about 15 to about 30%.
