Abstract
The invention discloses a comprehensive treatment and utilizing process for waste zinc slag, belongs to the comprehensive utilization technique of metal smelting waste, and particularly relates to a comprehensive utilizing technique for the waste zinc slag. The comprehensive treatment and utilizing process for the waste zinc slag is characterized in that flotation, magnetic separation and tailing processing are adopted for achieving comprehensive treatment of zinc slag. According to the comprehensive treatment and utilizing process for the waste zinc slag, the zinc slag can be treated comprehensively, pollution influences on the ecological environment brought by the zinc slag are eliminated, the metals of iron, copper, silver, gold and the like can be recycled and reused, the value of the zinc slag is promoted, in addition, the waste can further be made into building materials, and resources are effectively recycled.
Description
Technical field
The invention belongs to the comprehensive utilization technique of Metal smelting waste, especially a kind of comprehensive utilization technique of zinc slag.
Background technology
Cadmia is to smelt in the process of zinc ingot metal or the solid slag producing in the surplus material of rotary kiln evaporation zinc oxide, and iron content, copper, gold and the metallics such as silver-colored conventionally in this solid metallurgical slag, have suitable comprehensive utilization value.
Yunnan is the abundant area of nonferrous metal ore, plumbous, the retained reserve of zinc occupies the 1st, the whole nation, from eighties of last century, start just plumbous zinc ore to be developed and utilized the fifties, but up to the present but also there is not an efficient processing method cadmia can be carried out to treatment and comprehensive utilization, most zinc slags are still stacked for a long time, land occupation not only, and can impact ecotope, therefore need to research and develop a scientific and reasonable comprehensive utilization technique, cadmia is carried out to overall treatment utilization, not only can reduce the harm to environment and human health, can also therefrom obtain rich profit.
Existing cadmia treatment process, only limits to precious metals in cadmia, and as silver, iron, gold or copper extract again, remaining material still just becomes solid waste to be stacked, and fails to realize whole cadmia is processed, and realizes integrated application.
Summary of the invention
The object of the present invention is to provide a kind for the treatment of process of cadmia, the cadmia of stacking is for a long time fully utilized, after extraction iron, silver, gold or copper, leftover materials are processed formed material of construction again.
The comprehensive treating process of zinc slag of the present invention utilizes technique, it is characterized in that the processing of this process using flotation-magnetic separation-tailings realizes the comprehensive treating process of cadmia, is specially:
Flotation: floatation process is to adopt corresponding flotation reagent to select the gold and silver in zinc slag or copper, the material of residue iron content;
Magnetic separation: select iron ore through three grades of magnetic methods;
Tailings is processed: the tailings drying through magnetic separation becomes material of construction, and this material of construction comprises as cement admixture, concrete inert filler or is processed into aerated bricks.
Comprehensive processing technique of the present invention, cadmia can be carried out to overall treatment, not only eliminated the pollution effect that cadmia brings to ecotope, can also reclaim the metals such as iron, copper, silver, gold, by its re-using, promote it and be worth, waste can also be made material of construction in addition, has realized the effective recycling of resource.
Accompanying drawing explanation
Fig. 1 is the process flow sheet that the embodiment of the present invention 1 is processed into aerated bricks.
Embodiment
Embodiment 1: 1 ton of a kind of cadmia, and about cupric 0.515%, argentiferous 30-40 gram, containing 0.16 gram of gold, iron content 23%, carbon containing 6--8%, containing zinc 2%, siliceous 15% and calcic 3%.Wherein the form that exists of iron is, magnetite 3%, spathic iron ore 8.3%, ferric metasilicate 6.6%, pyrite 3.4% and hematite-limonite 1.7%.Through following processing step, its comprehensive treating process is utilized.
Flotation:
More than 90% cadmia is crushed to granularity and is less than 200 orders, pulp density 67%, through roughly selecting, triple cleaning and three processes of scanning floatingly select copper ore concentrates, the rate of recovery of copper is at 50-52%.The recyclable over 80 kg copper ore concentrates of 3.5%, one ton of cadmia of copper ore concentrates cupric, is worth 140 yuan.
Wherein, the medicament adopting in flotation is: 50 grams/ton, sodium sulphite, 80 grams/ton of the powerful activation of gold and silver collecting medicaments, yellow 200/ ton of collecting agent fourth for activator, 100 grams/ton of butylamine, 30 grams/ton of aniline, 5 grams/ton of No. 2 oil of pore forming material.
Magnetic separation:
The later mine tailing of the complete copper of flotation adopts three grades of magnetic separation to select iron ore, one-level magnetic separation strength be 2200 height hereby, secondary magnetic separation intensity be 1200 height hereby, three grades of magnetic separation are selected is secondary mine tailing, intensity be 1200 hereby high.
Residuum iron content after magnetic separation more than 15%, 90% is ferric oxide, silicon, calcium, aluminium, copper zinc, silver etc.Cadmia per ton reclaims 140 kilograms of grades 62% of iron ore concentrate, is worth 84 yuan.
Tailings is processed:
Tailings drying through magnetic separation becomes material of construction, and this material of construction comprises as cement admixture, concrete inert filler or is processed into aerated bricks, specific as follows:
(1) as cement admixture: levigate to 350 orders after directly the tailings of grog gypsum and oven dry being mixed;
(2) as concrete inert filler: the mine tailing of drying levigate to 200 orders above;
(3) be processed into aerated bricks: add respectively lime, containing silica sand and tailings, and add certain aluminium powder, by the complete processing of aerated bricks, be processed into light block, autoclaved brick.
The raw material cadmia of technique of the present invention is worth per ton at 40 yuan, through art breading of the present invention as the mine tailing value per ton of material of construction at 24 yuan, nearly more than 200 yuan of the income of iron copper, remove cost, cadmia per ton has suitable economic worth, and what is more important can also reduce its occupation of land by the waste residue that pile up like a mountain after comprehensive utilization, and to surrounding environment, comprise the pollution of soil and water body.Therefore, technology of the present invention has significant beneficial effect.
