Abstract:

The gold grade of arsenic bearing gold concentrate purchased by a gold smeltor is less than 30 g/t,if entering into the metallurgical process directly,it will not only affect the balance of process,but also increase production cost.According to the planktonic characteristics of arsenic minerals,the arsenic concentration was pre-selected after regrinding arsenic bearing gold concentrate under the condition of pH=3.5.The high grade gold concentrate with 51.11% yield was obtained by one roughing and twice selection,of which gold content is 48.10 g/t,sulfur content is 32.56%,arsenic content is 7.13%,arsenic recovery rate of 90.61%.Finally,the separation and enrichment of arsenic,sulfur and gold in arsenic bearing gold concentrate were achievedby the pretreatment process.It reduces volume of subsequent metallurgical operations,helps to improve metallurgical indicators and comprechensive benefits of enterprises,so as to achieve clean production,energy saving and emission reduction goals.

Key words: arsenic gold concentrate, acid, flotation tests, pretreatment, separation, enrichment, energy conser-vation and emissions reduction
