TL;DR: In this paper, an extraction process of iron mine sintered smoke dust valuable elements is described, which is capable of effectively extracting potassium, copper and silver, and has good social benefit and economic benefit.
Abstract: The invention discloses an extraction process of iron mine sintered smoke dust valuable elements. The process comprises the following steps: a, adding water to titanium dioxide waste acid to prepare an acid solution, and then adding sodium dodecyl sulfate and iron mine sintered smoke dust to perform leaching to obtain lead skim and leaching liquor; b, extracting the leaching liquor to obtain a copper-containing extracted organic phase and raffinate aqueous solution; c, adding sodium bromide to obtain silver bromide sediment and a filtrate; d, washing and drying the silver bromide sediment to obtain a silver bromide product; e, adding sodium carbonate, activated carbon and polysilicate ferric aluminum to the filtrate to obtain a colorless and transparent filtrate; f, adding sodium chlorate, and filtering to obtain a potassium chlorate product; adding the filtrate into the colorless and transparent filtrate obtained in the step e to use; g, when the mass concentration of sodium in the filtrate obtained through filtering and separating in the step f is greater than 280g/L, evaporating, concentrating and crystallizing to obtain an industrial sodium chloride product. The process disclosed by the invention is capable of effectively extracting potassium, copper and silver, and has good social benefit and economic benefit.

TL;DR: In this paper, a simple method for the determination of chlorate in the presence of a large amount of perchlorate is described, where the solution containing the mixture is acidified with either sulphuric acid or hydrochloric acid and titrated in the case of sodium bromide directly against titanous chloride using quinoline yellow as indicator near the end point.
Abstract: A rapid and simple method is described for the determination of chlorate in the presence of a large amount of perchlorate. The solution containing the mixture is acidified with either sulphuric acid or hydrochloric acid and titrated in the presence of sodium bromide directly against titanous chloride using quinoline yellow as indicator near the end point. The limit of uncertainty of the method is 0.361 mg for a sample analysing 52.48 mg of sodium chlorate.

TL;DR: In this article, the authors proposed a novel process for effective extraction of valuable metals (V, Cr, Ti, Mn, Fe, Al, and Mg) from the vanadium slag.
Abstract: In the present work, a novel process for effective extraction of valuable metals (V, Cr, Ti, Mn, Fe, Al, and Mg) from the vanadium slag is proposed. The leaching parameters for valuable metals extraction from the vanadium slag by acidic sodium chlorate solution were studied to obtain conditions for vanadium to be leached without using a pyro metallurgical step since the roasting process requires high energy consumption. The optimal H2SO4 concentration, weight ratio of NaClO3 to sample, leaching time, leaching temperature, agitation speed and ratio of liquid volume to solid mass were 6 M, 0.2, 6 h, 95oC, 200 rpm and 10, respectively. Under these optimal conditions, the extraction ratio of vanadium and valuable metals (V, Cr, Ti, Mn, Fe, Al, and Mg) were 85.8% and 91.2%, respectively. Compared with salt roasting, this process could simultaneously extract valuable metals from vanadium slag. More importantly, the experimental temperature was low underwater bath conditions. .

TL;DR: An oxidant for dyeing of a sulfide dye comprises components of sodium chlorate, sodium vanadate or ammonium vanadates, sodium chloride and water for adjusting concentration as discussed by the authors.
Abstract: An oxidant for dyeing of a sulfide dye comprises components of sodium chlorate, sodium vanadate or ammonium vanadate, sodium chloride and water for adjusting concentration. The part of weight of each component is that sodium chlorate 10-80 parts, sodium vanadate or ammonium vanadate 0.5-10 parts, sodium chloride 1-60 parts, the remaining part is water, wherein the use environment of the oxidant is that a dye vat of a jig dyeing machine contains 0.5-4% (o.w.f) of oxidant, 98% of acetic acid or 30% of sulfuric acid 1-6% (o.w.f) and four to six paths (note: the distance of one path is from one end of a roll of dye cloth to the other end of the roll of dye cloth in the dye vat), and temperature is 60-65DEG C. The oxidant for dyeing of the sulfide dye selects chlorate with low price to serve as an oxidation treatment agent, solves the problem of serious environment pollution caused by traditional sodium dichromate oxidation treatment, color fastness and hydrophilism are good, convenient conditions are provided for treatment after dyeing, repeated water washing and multiple soaping and color toning are not needed after oxidation treatment, and the problems of cloth surface sour, rough touch and dark color and light are solved.
