3. sodium sulfide is used as the activator of zinc oxide ore, and fatty amine is used to float zinc oxide minerals in alkaline medium. for mixed ore, the principle process of “lead before zinc” or “sulfur before oxygen” can be adopted. that is flotation sequence as following: galena lead oxide mineral sphalerite zinc oxide.
4. conclusions. from the above findings it can be concluded that: 0.6 tio 2 / 0.4 rgo composites were synthesized by a ball mill method. sem and x-ray analyses confirmed that reduced graphene oxide is well distributed on tio 2.these composites exhibited a reversible magnesium storage capacity and accepted cycling performance when applied as a cathode material in mg-ion.
According to a preferred embodiment of the invention the lead oxide chosen is lead dioxide pbo.sub.2 in a quantity between 5 and 15% by volume. lead is chosen from all dioxides which lead oxides of which the degree of oxidation is larger than 2 functioning as the oxidation agent referred to above, for example pb.sub.2 o.sub.3, pb.sub.3.
Alternatively, mixed lead oxides recovered from battery lead oxide pastes are mixed with carbon and smelted directly in a furnace to make molten lead. then the resulting lead in ingot form is shipped to a plant which has a barton reactor or ball mill process to be oxidized to the leady lead.

E. sheha et al. 179 is a semiconductor material (e g = 2.4 ev), where tuning of fermi level due to ion inser- tion is expected. the intercalation reaction of mg in v 2o 5 can be written as follows: xx mg v o mg v o . 25 25 + ↔+ − during this reaction the vanadium atoms are partially reduced from a v5+ to a v+4 formal oxidation state ..
Flotation process of lead-zinc oxide ore. 09-09-20; 43 views; icon 0; flotation process of lead-zinc oxide ore . the reason why lead-zinc oxide ore is difficult to select is mainly caused by the following two reasons: first, the composition of lead-zinc oxide ore is relatively complicated, including a large amount of soluble salts such as gypsum, copper sulfate, zinc sulfate, and carbonate.
In the flotation process of oxidized lead-zinc ore, sulfide is added first to vulcanize the mineral for subsequent flotation treatment. the following problems should be paid attention to in the vulcanization treatment of lead oxide: first, white lead ore, lead alum and lead molybdate are easy to vulcanize, sodium sulfide, calcium sulfide.
