Sulphur recovery from low grade ore has been achieved by solvent extraction
method, in a differential, continuous extractor. The mathematical models,
describing the differential extraction, have been adapted by attributing nu
merical values to its parameters. Additional measurements for equilibrium c
haracteristics are needed. Simulations have been performed to study the inf
luence of temperature, liquid/solid ratio and conveyer speed on the extract
ion efficiency. The results, represented in graphs, illustrating the correl
ation between the extraction efficiency and the working parameters are in g
ood agreement with the experimental data. (C) 1999 Elsevier Science Ltd. Al
