Objectif PRODUCTION OF A COMMERCIAL GRADE ZINC CONCENTRATE FROM THE POOR SMITHSONITE AND CALAMINE ORES OF SEVERAL GREEK DEPOSITS. AT SEVERAL PARTS OF GREECE AND PARTICULARLY ON THE ISLAND OF THASSOS THERE ARE LARGE DEPOSITS OF LOW GRADE SMITHSONITE AND CALAMINE. THE BENEFICIATION OF THESE MINERALS HAS NOT BEEN ACHIEVED AS YET. THE PROPOSED RESEARCH WILL EXPLORE THE POSSIBILITY OF THE PRODUCTION OF A COMMERCIAL GRADE ZINC CONCENTRATE. THE RESEARCH WILL INCLUDE CHEMICAL AND MINERALOGICAL ANALYSIS AND THE FOLLOWING LABORATORY ORE DRESSING METHODS : - CRUSHING AND SCREENING, ANALYSING CRUSHING PROPERTIES AND PARTICLE DISTRIBUTION - HEAVY LIQUID SEPARATION, DETERMINATION OF APPLICABILITY OF A PRECONCENTRATION-STEP - FLOTATION TEST WITH DIFFERENT AGENTS - LEACHING BY CAUSTIC SODA, TESTING BY BACTERIAL LEACHING AN ECONOMIC EVALUATION OF THE MOST PROMISSING PROCESSES WILL BE MADE.
