Description
Technical field
The present invention relates to the recycling field of industrial residue and waste liquid, be specifically related to a kind of method of utilizing manganese leached mud and electrolytic manganese spent acid to prepare superfine active carbon white.
Background technology
Manganese is to produce iron and steel and stainless raw material, is subjected to the pulling of Iron and Steel Production sustainable growth, and China is constantly soaring to the demand of manganese ore.China is iron alloy producing country as maximum in the world manganese, and manganese matter alloy output reached 7,450,000 tons in 2008.China is that manganese resource is stored profuse country, but the average grade of manganese ore is lower, and the manganese ore reserves in the whole nation 93.6% belong to poor manganese ore.According to statistics, 1 ton of manganese of every electrolysis production will produce 6～7 tons of manganese leached muds and a large amount of spent acid, and, along with the acceleration of manganese ore exploitation and the continuous increase of manganese demand, produce the residue contamination that manganese produced and be on the rise, therefore the research that manganese leached mud and spent acid are recycled is imperative.
The relevant report that present domestic manganese leached mud is handled concentrates on fields such as preparation material of construction, 4A molecular sieve mostly, and these technologies all will be through the operation of high-temperature calcination, the production cost height, and the value-added content of product that obtains lower, essentially no economic benefit; Therefore utilizing manganese leached mud supervene value high product and production technique thereof will be the development trend that manganese ore industry waste residue is handled.
White carbon black is widely used in packing strengthening agent, printing ink thickening material, paint additive, synthetic grease and silicone grease viscosifying agent, curriery flatting agent, pesticide dispersing agent, the papermaking weighting agent of rubber, plastics, the fields such as additive, electric industry insulation and thermal insulation filler and daily-use chemical industry raw material of synthetic resins (alkyd resin, elasticity Polyurethane).Superfine active carbon white as rubber reinforcing filler can improve vulcanized rubber article tensile strength, hardness, deflect, tear, abrasion, ageing-resistant performance, be light color, colour and the indispensable high-quality reinforcing filler of transparent rubber goods, be widely used as the reinforcement of products such as colored rain boots, sports shoes, transparent adhesive tape sole, tire, rubber roll, cable; Strengthening agent as the plastics boardy product can improve its solidity to corrosion, weathering resistance and levelling property.Have relevant expert to estimate, under the drive of tire and shoe industry, Chinese dialogue sooty demand will increase fast with annual 8%～10% speed; The price of white carbon black is then more little because of particle, the big more price of specific surface area is high more.Chinese patent ZL200610035724.5 once reported and utilizes the less white bauxite waste residue of impurity to prepare active carbon white, but its silicon-dioxide is mainly used in the rubber materials that tensile strength is less demanding, productive rate is lower.So far do not see as yet have with more brown manganese leached mud of impurity and electrolytic manganese spent acid be main raw material prepare particle diameter little, easily be scattered in rubbery system, keep rubber that the report of the superfine active carbon white higher than high tensile, added value is arranged.
Si is (with SiO in the manganese leached mud
2Meter) content reaches 22～30wt%, and the waste acid liquor behind the electrolytic manganese can not directly discharge because of acid concentration is higher, so processing and utilize these waste residues, waste liquid that environment protection is become more important; Prepare superfine active carbon white with method of the present invention simultaneously and can satisfy market demand, obtain economic benefit, can also solve the trouble and worry of electrolytic manganese dioxide manufacturer, help environment protection.
