Composition and processing of sulphide lead-zinc ores from Chaabet El-Hamra mine (Setif, Algeria)

Purpose. In order to fully exploit the metal and facilitate its method of processing, we need an accurate knowledge composition, granular distribution, association with unimportant penalizing elements that would like get rid of, compared distribution element extract by flotation method. Methodology. The present experimental work proposes approach mineralogical, chemical particle size characterization, several analyzes have been carried out Scanning Electron Microscopy Energy Dispersive Spectroscopy (SEM/EDS), X-ray Diffraction (XRD), Optical (OM), Particle Size-Fraction Analysis (PSFA), Fluorescence (XRF). These were submitted on samples lead-zinc different sizes as well well-prepared fine powder this ore; zinc content raw material is about 5% Zn. Findings. results obtained mineralogical characterization analysis reveal a very varied irregular texture ore, consisting mainly sulphides (sphalerite, galena, pyrite, marcasite), associated carbonate gangue, dolomite calcite. theoretical dimensions particles found in grain classes [-1 +0.053] mm. addition, conditions pulp using following reagents: CuSO4 activator, PAX collector, CaO regulator pine oil foamed, along pH modifier between 10.5 12 (11.8 optimal), improve sulphide minerals, increased concentrate sphalerite (ZnS) foam Flotation maximum recovery economically appropriate (54% Zn concentrate). Originality. Depending performed complete collection data laboratory, aim optimize process treating ore give more detailed reference source specialists, researchers metallurgists field mining general treatment polymetallic area studied particular. Practical value. Benefit values beneficial minerals (concentrate others sulphide), from types materials. latter focuses main successful technique extraction type but it requires constant research careful examination excel polymetallic-sulphide processing.
