These technogenic waste
is generated in the production of titanium dioxide by etching iron steel
industry. In the world of their accumulated at least a billion tons. For
example, in JSC "Crimean Titan" crowded slurry tank covers an area of
45 square kilometers, and in the tailings pond of "Sumykhimprom" as a
result of the production of titanium dioxide pigments accumulated more than 2
million. tons of ferrous sulfate FeSO4 doped with sulfuric acid.
We can offer method for processing of waste
sulfuric acid titanium production with extraction of Fe2O3
and H2SO4, when using additional raw materials and
associated production of Cl2, K2SO4, (NH4)2SO4.
The composition of the additional raw materials and manufactured commodity
products may vary.
The difference cost of raw materials
and products is quite significant to not question the wisdom of recycling of
waste sulfuric acid.
We would welcome your help in editing English pages on our site.
