SU105759A1 - Method for determining minimum copper sulfate consumption to activate zinc blende - Google Patents

Description

Determining the consumption of copper sulphate used for activating zinc is important for the results of the following: followed by zinc flocacin. It is known that, due to the lack of copper sulfate, zinc losses in the flotation tails are extremely increased. Excessive vitriol is also very harmful: in addition to the activation of pyrite, excess copper sulfate impedes foaming, causes over-consumption of the collector and foaming agent and degrades the quality of the zinc concentrate.

A specific feature of the proposed onlinele1H1 method of minerum copper sulfate consumption is the use of copper ammonium solution of vitriol from the ammonium water solution used as an indicator of this consumption of ammonium sulfate known to the end of 1 gracine, adding to the aerated zinc loading of Mancoy, after which The spent solution is used to calculate the specific consumption of copper sulphate.

A sample of pulverized feed flotation or lead flotation tailings is loaded into a laboratory flotation machine with a rotating impeller; lime and xanthate are also added thereto in the usual form of zinc floganium ore of this ore (no frother is introduced). Then, when aerating is pulverized, a water-ammonia solution of copper sulfate of known concentration is gradually added to the machine from the burette. When its quality becomes sufficient to activate zinc blende, the color of the foam in the flotomaing does not change, the foam is loaded with blende, the height of the foam is slightly reduced, and the village ore is partially i.e. fully nrevravogogs (with an impregnated film.

If there are several varieties of zinc blende in the ore, for example, light with a low content of iron and dark with a high content of iron, then the first one appears and appears in the yen as a low-selling zinc blende; after this, one should additionally add a water-ammonia solution of copper sulphate until it appears in the foam and dark zinc blende with higher

iron content so that

the color of the foam film was about the same as that of the zinc flotation of this ore. ..

The minimum amount of copper sulphate, which is necessary for a similar change in the nature of the yen, i.e., a transition from a half-empty foam tailing lead flotation to an intense foaming zinc foaming film, is minimal chimp-activated for activation.

It takes 3-5 minutes to complete a lotto titration.

A ammonia vodka of copper sulfate can be prepared, for example, in the following way: 2 g of copper sulphate is placed in a volumetric flask () 200 ml, added to the bottle; 1 is the usual amount of water, the fashionable vitriol is dissolved in chilled water; then an ammonia coprecipitate solution is added dropwise until

The initially precipitated blue precipitate does not completely dissolve to form a blue-violet solution, after which the flask is filled to the mark with water and stirred. The resulting solution is used d,: (implementation of the proposed method; I ml of this solution of soda) contains 10 mg of copper sulphate.

The subject of the invention. The method for determining the minimum consumption of copper sulfate, necessary for activating a zinc coating, is also required so that a water-ammonia solution of copper sulfate of a known concentration added to aerated liquid is used as an indicator of this consumption. the pulp to a sharp increase in the loading of the soil deodorization, after which the specific consumption of the medic vitriol was calculated on the cost of the spent solution.
