Fig. 3 Flowchart of slag calcification and chlorination of jarosite residue
raffinate is extracted by copper extraction—electrowinning to obtain cathode copper.
Zinc chloride products obtained by indium replacement post solution purification and
remove impurities evaporation crystallization. It realizes the effective separation of
lead, zinc, copper, silver, and silver elements. It can be made into a saleable product
realizing the comprehensive utilization of jarosite residue. The process flowchart is
shown in Fig. 3.
Reagents: jarosite residue, calcium chloride, coal powder. Instruments: X-ray
diffractometer, thermogravimetric analyzer, inductively coupled plasma optical
emission spectrometer. The elemental composition of jarosite residue was analyzed
by inductively coupled plasma optical emission spectrometry (ICP-OES). The new
technology of calcification and chlorination volatilization of jarosite residue is mainly
to study the chlorination volatilization of valuable metals such as lead, zinc, copper,
silver, and indium under the action of chlorinating agent. Also, the enrichment of
iron elements in the slag can be used in ironmaking system after magnetic separation
or other enrichment.
