Objective
Treatment of jarositic wastes from the zinc industry is a costly procedure,whereas storage in lined basins will eventually result in leakage of heavy metal containing solutions to the groundwater and, thus, pose a threat to the environment. A novel technology(the JARMEST process)treating the jarosite wastes with organic waste streams,was invented by one of the partners to this proposal. The process has been tested in laboratory experiments which produce a solid waste with high metal concentrations and a relatively clear effluent with low metal concentrations. The tests strongly indicate the viability of this waste-to-waste process on an industrial scale. The proposed research concerns the further development into a continuous process,using a vertical high pressure reactor,and should result into a low cost,energy-efficient decontamination technology with the benefits of the recovery of a considerable amount of metals contained in the jarositic waste. The major tasks of the research are grouped as follows:
-test runs on laboratory scale with jarosites of different composition.
-characterization and metallurgical treatment of the solids resulting from the reaction; recycling and/or immobilization of the contained metals.
-decontamination to environmentally acceptable standards of the effluent.
-upgrading of the process to a (semi)-continuous scale in the vertical reactor.
-economic and technical evaluation and basic design of a pilot plant.
