Embodiment 1
[0027] A process for processing refractory gold ore, comprising the steps of:
[0028] The refractory gold ore is crushed by a crusher, then sent to a ball mill, and ground to a particle size of 200 mesh ore powder, wherein an activator is added to the ball mill, and the amount added is one thousandth of the mass of the gold ore; the activator is in accordance with Sodium silicate: kerosene is mixed at a mass ratio of 1:1; water is added to adjust the mineral powder concentration to 30% (w / v) ore slurry, and then hydrogen peroxide is added to the ore slurry and stirred evenly, wherein hydrogen peroxide and ore The volume ratio of the slurry is 1:200.
[0029] Put the bacterial agent into the ore slurry, wherein the mass ratio of the bacterial agent to the ore slurry is 1:100; stir while feeding the air, the stirring speed is 200 rpm, and the amount of air per minute is 0.5m 3 / m 3 The ore slurry is subjected to microbial catalysis under the condition of 30° C., and the catal...
Embodiment 2
[0034] The gold mine selected as the material is a high-sulfur, high-arsenic and high-carbon gold mine in Shandong Province. The main metallic minerals are arsenopyrite and pyrite, and the main non-metallic minerals are quartz, graphite and carbon. The main element analysis results of the ore samples are shown in Table 1.

[0049] Bacteria effect test:
[0050] Comparative test: divided into three control groups, specifically Control 1, Control 2, Control 3, and Example 2 of the present invention.
[0051] Control group 1: the bacterial agent is acidophilus Thiobacillus ferrooxidans and acidophilic sulfur bacteria according to the ratio of 1:1, the amount of sodium cyanide is 5kg / t, and the rest are the same as in Example 2; Control group 2: the microbial agent is Acidophilus Thiobacillus ferrooxidans, acidophilus Thiobacillus and Leptospira ferrooxidans were prepared according to the ratio of 1:1:1, the amount of sodium cyanide was 2kg / t, and the rest were the same as in Example 2; Control 3: no addition Hydrogen peroxide, the processing method is general embodiment 2. The desulfurization rate, arsenic removal rate, decarburization rate and gold leaching rate were obtained through detection, see Table 2.
