Rude ores, which were collected from two lead-zinc oxide ore deposits in Sichuan province, are very difficult to process with low grade and uneven mineral dissemination. It is very difficult to separate valuable minerals from gangue minerals, especially for the recovery of lead and zinc minerals. On the basis of mineral characteristic study, author studied flotation technology on lead-zinc mineral, and gained satisfactory concentrate indicator by stage-grinding: the lead concentrate with a grade of 52.45 percents and a recovery of 79.30 percents and the zinc concentrate with a grade of 35.26 percents and a recovery of 87.57 percents .

Ore samples, collected from a lead-zinc oxide ore deposit in Sichuan province, China, are very difficult to treat with such characteristics as low grade, uneven mineral particle distribution and high containing of slime. It is very difficult to separate the lead minerals and zinc minerals, especially for the recovery of zinc oxide minerals. On the basis of flotation characteristics study to gangue and useful minerals, author studied flotation behavior of lead-zinc oxide ore with new collectors (KM21 and YO-1), and carried out the experiment on separating useful minerals from gangue minerals. Test results showed, a lead concentrate with a grade of 59.78 percent and a recovery of 86.49 percent and a zinc concentrate with a grade of 48.53 percent and a recovery of 84.92 percent were obtained from the crude ore with the oxidation rate of 74.34 percent and 89.30 percent of lead and zinc respectively, which realized the high efficient flotation separation of the refractory lead-zinc oxide ores.

AbstractCollector type and pulp pH play an important role in the lead–zinc ore flotation process. In the current study, the effect of pulp pH and the collector type parameters on the galena and sphalerite flotation from a complex lead–zinc–iron ore was investigated. The ethyl xanthate and Aero 3418 collectors were used for lead flotation and Aero 3477 and amyl xanthate for zinc flotation. It was found that maximum lead grade could be achieved by using Aero 3418 as collector at pH 8. Also, iron and zinc recoveries and grades were increased in the lead concentrate at lower pH which caused zinc recovery reduction in the zinc concentrate and decrease the lead grade concentrate. Furthermore, the results showed that the maximum zinc grade and recovery of 42.9% and 76.7% were achieved at pH 6 in the presence of Aero 3477 as collector. For both collectors at pH 5, Zinc recovery was increased around 2–3%; however, the iron recovery was also increased at this pH which reduced the zinc concentrate quality. Finally, pH 8 and pH 6 were selected as optimum pH values for lead and zinc flotation circuits, respectively.

The tailing in a large lead-zinc-iron-sulfur multi-metallic mine has rich reservation in variety of metallic minerals. It has been difficult to recover because of all kinds of reasons. The challenges faced by lead-zinc ore beneficiation are, low grade and recovery of lead and zinc concentrate for fine disseminated grain size, high oxidation rate and close intergrowth. This paper presents a Pulp Potential Control Flotation by stages technique to improve the flotation performance of the lead-zinc ores. In the electrochemical potential controlling flotation processing, using DDTC as collector, the separation potential range of galena and sphalerite with pyrrhotite can be achieved. Flotation circuit of lead-zinc-silver tailing ore was achieved.

Detailed characterisation and recovery of galena, sphalerite, and pyrrhotite from the beneficiation plant tailing of YouXi, China, was investigated. Different characterisation techniques viz. size analysis, chemical analysis, mineral analysis by Mineral Liberation Analyser（MLA）were carried out. Based on the appreciable differences in specific gravity, floatability and magnetic susceptibility between the desired lead, zinc, sulphur minerals and the gangue minerals, the flow sheets comprising desliming, flotation and magnetic separation, was used to recover galena, sphalerite, and pyrrhotite values. A lead and zinc concentrate of Pb 16.02%, Zn 35.1% and sulphur concentrate assays 35% S and 56% Fe can be produced from the tailing.

The authors carried out a mineralogical study and substantiated a concentration process developed for the lead-zinc ores of the Pavlovsk deposit. The concentration of the valuable component in each type of concentrate is determined by the amount of pyrite contained in the ore. It was established that the main loss of lead with flotation tailings is associated with oxidized phases, which are mainly found in fine material. Lead sulphides account for 30% of the entire waste tailings. Using the results of the mineralogical study, a flotation process was developed that involves a staged separation of commercial lead and zinc concentrates, as well as waste tailings. The obtained zinc concentrate has a consistently high quality of 57–58% with an 85–90% recovery. The metal concentration in the lead concentrate 1 is 45%, with the recovery being 43%. On the basis of the experimental results, the authors propose to use an X-ray radiometric separation method for coarse ore, which will help reduce the amount of incoming ore by 30% while minimizing the loss of lead and zinc.

The paper discusses the lithological and facial features of the terrigenous-carbonate (biohermic) ore-bearing geological formation of the Moryanikho-Merkurikhinskoye ore field (Yenisei Ridge), which hosts stratiform lead-zinc deposits in carbonate strata. Ore-hosting lithofacies and their paleostructural position are characterized. Based on the previous studies, as well as the author’s own materials obtained as a result of field work, the main favorable lithological, facial and structural factors for hosting Moryanikhinsky-type stratiform lead-zinc mineralization are defined: the presence of paleodepressions within the shelf zone; development of carbonate rocks – dolomites, stromatolite dolomites and limestones, which are biohermic structures on the slopes of paleo-uplifts; the presence of an admixture of tuffaceous material in terrigenous rock varieties. The influence of tectonic faults on the formation of ore deposits and the morphology of ore bodies is indicated. The main types of ores of the Moryanikho- Merkurikhinsky ore field, as well as their mineral composition are described. The paper discusses the main ore types, as well as their mineral composition typical of the Moryanikho-Merkurikhinskoye ore field. The largest and well-studied lead and zinc stratiform Moryanikhinskoye deposit and Merkurikhinskoye ore occurrence located within the ore field are briefly characterized. The Moryanikhinskoye deposit is a typical example for searching for stratiform deposits of lead and zinc in the carbonate strata of the Angara-Bolshepitskaya mineragenic zone, which is of practical interest in developing predictive prospecting models of deposits and improving the efficiency of prospecting.
