By the side-submerged combustion smelting technology, the smelting temperature
increases from 1200 to 1300–1400 °C. The actual standard of coal consumption is
30–40% lower than other treatment processes.
Conclusions
(1) In the coming years, the global zinc demand will continue to exceed the zinc
production. The treatment of zinc slag (including zinc smelting slag and zinc
leach residue) is more and more important to improve global zinc production
and environmental protection.
(2) Due to the complex composition of zinc smelting slag and the low content of
valuable metals, the economic and efficient recovery of polymetallic elements
can be realized by the hydrometallurgical process. Zinc smelting slag produced
by ISF can be used as a building material by the geopolymerization process.
(3) Side-submerged combustion smelting technology has been successfully industrialized to treat the zinc leach residue. The technology can simplify the process
of zinc leach residue treatment, save energy, and reduce consumption. And it
has a broad application prospect.
