Abstract

Samples of waste recycling smelting slag dumpare selected. The chemical, mineralogical and phase composition of the slag is studied. According to X-ray diffraction
almost all of the copper is concentrated in ferrites and
zinc – in ferrites, silicates, zincite and sphalerite.
An attempt was made to divide slag into the magnetic
and non-magnetic fractions by wet magnetic separation.
The synthesis and study of iron glass, similar in composition to glandular glassy phase smelting slag is made.
Studies have been conducted on leaching of copper and
zinc ferrite from the SUMZ slag by agitation leaching
with sulfuric, nitric and hydrochloric acids. Most copper
and zinc extraction is observed in comparatively weak
solutions of sulfuric acid. Experiments on the kinetics of
ferrites dissolution by a rotating disk are durable and
currently ongoing.
