Description

During flotation as flotation reagents, they are substances of different origin, possessing a certain batch activity in solutions and capable of forming CTOIIKVIO not. As is well known, some of the animal proteins are among these veins, and they are not used in the flotennius. since there is little doetuin and road.

Of great interest in this regard are the derivatives of animal proteins, which are processed in various ways, 1 is in a meaty manner. Of these derivatives, it is particularly important that eulfonaphgenic UOCO-soluble proteins, which are obtained according to the method of organic protein auth. ev Lz 53965.

In iipHMeiieHHii sulfo; 1 naphthenic derivatives of animal proteins or soluble B water, inorganic or organic, their salts are as flotation agents and consists of the specificity of its invention.

Products obtained but its autom. St. Lo 53965, are derivatives of gluten and b.trox krsmp ;, or so: az vaemn1 "supal bb and ;;.

The presence in the protein molecule of the sulfo-naphthenic group leads to the fact that not only the salts of the ethanol ;; of the first group, soluble under certain conditions, but also some of the derivatives of NoryT form a very stable way of collecting flotiruela of the theory. Here, the supersonic activity of the lingerie; and it is enhanced by the syphonaphthenic group.

The argument is dissolved. Oh.Yuchi i.ti u1 1acid co.ieii with lfonaphthenic derivative of any animal protein (kontakt.go k.te, e} L1albiya, etc.) to a certain RP, l OJ1; o sex chit1, f .: The reagent is capable of collecting peekol11ko meta.tl simultaneously simultaneously 1 selectively.

For the fleet, and more than 1 year, dissolved, 1e in water are the salts of these sulfonic naphthic hydroxides. In order to obtain P1 of these salts, the prod indicated. proteins are treated ia to cold or sludge with weak heating with such an alkali solution so that o6niee amount is 1x well. i.e. exceeds 2-3, by the penetrant of protein. For example, to dissolve 100 g of Sialb 1, you need 2-3 g of dry carbon

idedela, which can be applied as a 5% -iioro solution. After mixing the alkali solution with sialbioia, such an amount of water is added to obtain a viscous solution. This solution is kept until the protein derivative is completely dissolved. It is possible to replace dry suialbiia with dry sugar with alkali and add water to such a mixture until a copepods are obtained. ripiiMeiiHsi, instead of carbon dioxide, pure alkali metal hydrate, the dissolution process can be accelerated.

When dry and producing glutip, it is recommended to pre-allow it to swell in water and after that process it with alkali when heated. If derivative be. applied as an infusion, the latter should be pre-melted and the alkali solution should be introduced to the southern PMM in the ravenlav. mass. At the same time it is necessary to produce non-confusion. Water-soluble organic solvents can also be used instead.

The subject is invented and

The flotation method, which is based on the fact that eulfo-naphthenic production of animal proteins or water-soluble, peorgic or organic salts are used as flotation agents.
