Abstract
A method for desulfurization and dezincification of tailings includes the step of passing tap water into a high oxidation reduction electrocatalytic water equipment to reduce the pH value of tap water to 1-2, mixing a specific ratio of the pH value 1-2 acid electrocatalytic water with low-quality high-sulfur iron in the tailings, heating the mixture to let H+ in the acid electrocatalytic water be reacted with sulfur and zinc in the low-quality high-sulfur iron and to further cause generation of an ion state of hydrogen sulfide gas where the volatilization of water vapor effectively removes the sulfur and zinc elements in the low-quality high-sulfur iron and the hydrogen sulfide gas thus generated is collected.
Claims6
A method for desulfurization and dezincification of tailings, comprising the steps of:
- passing tap water into a oxidation reduction electrocatalytic water equipment for enabling the pH value of said tap water to be reduced to 1-2 so as to obtain a pH value 1-2 acid electrocatalytic water;
- mixing a specific ratio of said pH value 1-2 acid electrocatalytic water with said tailings to be treated subject to a specific formula;
- and
- heating the mixture of said pH value 1-2 acid electrocatalytic water and said tailings for a predetermined period of time to let H+ in said acid electrocatalytic water be reacted with sulfur and zinc in said tailings and to further cause generation of an ion state of hydrogen sulfide gas and sulfur dioxide gas where the volatilization of water vapor effectively removes the sulfur and zinc elements in said tailings to render iron ore therein suitable for steelmaking and the hydrogen sulfide gas and the sulfur dioxide gas thus generated are collected into an ultra-gas battery flow device through a pipeline;
- and
- reducing the collected hydrogen sulfide gas and sulfur dioxide gas to obtain water vapor and sulfur.
