[0033] Example 1
[0034] Taking a high-sulfur bauxite ore under coal in a certain area of Henan Province as the test ore sample, the chemical composition of the ore is shown in Table 1.
[0035] Table 1 High-sulfur bauxite mine under coal in a certain area in Henan
[0036] ingredientAl 2 O 3 SiO 2 Fe 2 O 3 TiO 2 K 2 O Na 2 O CaO MgOSC Discretionary content / %63.4612.352.642.961.100.0250.810.251.211.8013.40
[0037] The test process consists of a section of rapid chemical desulfurization underflow in parallel with two of the equipments for bioleaching desulfurization.
[0038] Process parameters: rapid chemical desulfurization grinding fineness of 78%-200 mesh, natural pulp pH value, chemical desulfurization agent dosage 400g / t, desulfurization temperature is normal temperature; chemical desulfurization underflow enters the second stage mill through the discharge port to the grinding The fineness is 92% -200 mesh. After entering the stirring channel, inoculate Thiobacillus fer...
