TL;DR: In this article, a method for rapidly determining total cyanides in cyanide-containing ore pulp, belonging to methods for rapidly determined the total cyanide in the cyanide containing ore pulp in a cyanidation technology of the gold industry, is presented.

TL;DR: In this article, a method for simply and efficiently determining a content of lead in gold concentrate was proposed, which consists of the following steps: dissolving a test sample by utilizing nitric acid-potassium chlorate solution, enabling lead in a sulfuric acid medium to form lead sulfate precipitates, filtering, dissolving the precipitates and finally summing the lead content in the filtrate and the lead contents in the precipitate, thus obtaining the content in ores.

TL;DR: In this article, a mass concentration determination method of easily released cyanide in thiocyanate-containing water was proposed, which consisted of carrying out primary distillation by the use of zinc nitrate and tartaric acid.

TL;DR: In this article, a method for determining easy-to-release cyanide in sulfide-containing based cyanidecontaining solid waste was proposed, and the method comprises the following steps: selecting sampling weight, adopting ethanol as a dispersing agent and adding distilled water to further increase dispersity of the cyanide containing solid waste; using zinc nitrate and tartaric acid as pre-distillation reagents for primary distillation, performing secondary distillation according to a determination method of total cyanide, and adding silver nitrate as a masking agent to remove sulfide,

TL;DR: In this article, a measurement method for total cyanide in solid wastes containing thiocyanate and sulfide is proposed, which consists of the following steps: selecting a reasonable weighing sample, using ethyl alcohol as a dispersing agent, adding distilled water to further increase the dispersibility of the cyanogens-containing solid wastes, adding silver nitrate to shelter the interference of thiocoyanate, and adopting a sodium hydroxide solution as absorption liquid.
