Problems solved by technology

Arsenic enters flue gas, waste water and waste residue in the state of sulfide or salt in the process of extracting non-ferrous metals. Most manufacturers cannot find a suitable treatment method, so they pile up a large amount of arsenic acid residue or use it as Discharged in the form of "three wastes", these arsenic-containing acid slags constitute the most important source of environmental pollution in nonferrous metallurgical enterprises in my country, and have a very bad impact on the surrounding environment of the enterprise, and their harmless treatment has become an urgent problem to be solved

Abstract

The invention discloses special gelatinization powder for acid-base resistant heavy metals. The special gelatinization powder is prepared from steel slag, furnace slag and a calcium intensified material. A preparation method of the special gelatinization powder comprises the following steps: (1) mixing raw materials such as the steel slag, the furnace slag and the calcium intensifying material, adding the mixture into a mill, and performing rough milling so as to obtain mixture granules; (2) performing high-temperature calcination on the mixture granules in a furnace, adding the calcium intensifying material to implement a chemical reaction in the high-temperature calcination process so as to obtain reaction granules; (3) performing fine milling on the reaction granules in the mill, and performing uniform stirring in the fine milling process so as to obtain mixture powder; and (4) screening the mixture powder in a screen net of 325-500 meshes, thereby obtaining screened fine powder, that is, the special gelatinization powder for the acid-base resistant heavy metals. The special gelatinization powder is mainly used underground and in exposed and corroded environments, the problem that poison-containing waste slag is hard to dispose is solved, and the purposes that poisonous slag is made into making building bricks or is deeply buried underground can be achieved.

Description

technical field [0001] The invention relates to a gelled powder, in particular to a special gelled powder for anti-acid and alkali heavy metals. Background technique [0002] Arsenic is a carcinogen that is toxic to the human body and other organisms. Although arsenic in nature exists as a single mineral, most of it is often associated with non-ferrous metal ores, and enters non-ferrous smelters with concentrates. Arsenic enters flue gas, waste water and waste residue in the state of sulfide or salt in the process of extracting non-ferrous metals. Most manufacturers cannot find a suitable treatment method, so they pile up a large amount of arsenic acid residue or use it as Discharged in the form of "three wastes", these arsenic-containing acid slags constitute the most important source of environmental pollution in nonferrous metallurgical enterprises in my country, and have a very bad impact on the surrounding environment of the enterprise, and their harmless treatment has ...
