Abstract
A method of economically, industrially, and effectively recovering sulfur from a leaching residue produced by leaching sulphide minerals (e. g. copper concentrates) under atmospheric pressure includes the steps of pretreating the leaching residue with an acid solution, and selectively recovering sulfur from the leaching residue by a flotation process.
Claims (6)
1. A method of recovering sulfur from a leaching residue produced by leaching sulphide minerals (e. g. copper concentrates) under atmospheric pressure, the method comprising the steps of:
pretreating the leaching residue with an acid solution; and selectively recovering sulfur from the leaching residue by a flotation process.
pretreating the leaching residue with an acid solution; and selectively recovering sulfur from the leaching residue by a flotation process.
2. The method as claimed in claim 1, wherein the acid solution is a sulfuric acid solution.
3. The method as claimed in claim 1, wherein the step of pretreating the leaching residue with an acid solution comprises the step of:
pretreating the leaching residue with a treatment solution of sulfuric acid having a pH value equal to or less than 1.5, at a pulp density of 10 to 50 mass percent, for a processing time of 20 to 60 minutes, and at a processing temperature of 30 to 90°C.
pretreating the leaching residue with a treatment solution of sulfuric acid having a pH value equal to or less than 1.5, at a pulp density of 10 to 50 mass percent, for a processing time of 20 to 60 minutes, and at a processing temperature of 30 to 90°C.
4. The method as claimed in claim 1, wherein the step of selectively recovering sulfur from the leaching residue by a flotation process comprises the step of:
applying the floatation process to the pretreated residue at a pulp density of 10 to 35 mass percent, in a treatment solution having a pH value equal to or less than 2.2, and at a processing temperature of 20 to 90°C.
applying the floatation process to the pretreated residue at a pulp density of 10 to 35 mass percent, in a treatment solution having a pH value equal to or less than 2.2, and at a processing temperature of 20 to 90°C.
5. The method as claimed in claim 1, wherein the step of selectively recovering sulfur from the leaching residue by a flotation process further comprises the step of:
applying a cleaner flotation to a product produced by the floatation process.
applying a cleaner flotation to a product produced by the floatation process.
6. The method as claimed in claim 5, wherein the step of selectively recovering sulfur from the leaching residue by a flotation process further comprises the step of:
if a product containing sulfur produced by the cleaner flotation includes sulfides which have not leached away, applying a gravity separation process to the product so as to selectively removing the sulfides from the product.
if a product containing sulfur produced by the cleaner flotation includes sulfides which have not leached away, applying a gravity separation process to the product so as to selectively removing the sulfides from the product.
