The comparative tests were conducted of surfactants as foaming agents during
the flotation of Cu-Mo ores on regime CCM. As a result, selected the best: PT-6,
PT-7, AP-3, AP-4, similar on effect flotation of Cu-Mo ore to the foaming agent T-
92 to carry out pilot plant testes. Foams generated
in solutions of synthesized
foaming agents meet on the dispersion of flotation foaming agent, but also they
have not met fully on stability yet, which was not still high, i.e. such foams must
provide flotation and then destroyed.

HMC-polymer SC from local anthropogenic raw was made for use as a
binder in the composition of mixture granulation of Mo concentrate on the basis of
current
issues of metallurgy, reducing the molybdenum concentrate dilution,
produced by JSC «Almalyk MMC». Decision it could be seen on towards its
replacement parts of kaolin into caustic for 10-12 h, at 95°С-105°С (Fig. 10).
The fusion mixture
was prepared based on kaolin, bentonite, sodium silicate
(LS), CK, Na-CMC (carboxymethyl cellulose), polyvinyl acetate (PVA),
sulfonated celluloses (SС). Their composition (binder,%
the rest is Mo
concentrate): №1 (without a binder), №2 (kaolin 10%), №3 (SC 3%), №4 (kaolin
2%, SC 3%) , №5 (bentonite 2%, SC3%), №6 (bentonite 2%, CMC 2%), №7
(bentonite 2%, PVA 2%), №8 (bentonite 2% SС 2%). №9 (SC 1%), №10 (SC
1.5%, GS
1.5%), №11 (2% bentonite, SC 1.5%, GS 1.5%), №12 (kaolin 2% , SC
1.5%, GS 1.5%), №13 (GS 3%); №14 (bentonite 2% CMC 0.5%); №15
(bentonite, 2%, SC 0.5%); №16 (kaolin 2%, SC 0.5%); №17 (bentonite 1%, CMC
0.5%), №18 (bentonite, 1%, SC 0.5%). Choosing the best fusion mixture was made
from comparing the strength of the granules before and after firing, and, based on
the residual content of sulfur in the candle end (Table. 7).
The advantage of
compounds based on the SC in comparing to mixtures without one is that polymer
burned during firing without causing dilution candle end.
