The ore compositions in a certain newly proven tin polymetallic ore are complicated, closely mosaic between different minerals and fine-grained disseminated. The main compositions in the ore exist mostly in the form of sulfide, and are associated partly with oxidized ore. It is difficult to separate each metallic mineral to accept qualified concentrates and ensure higher recovery rates. Aiming at characteristics and occurrences of the ore, the project emphatically selects and contrasts the test flow of selective flotation, partial bulk flotation and flotation-and-gravity-concentration, and uses effective reagent system to control the impurity contents in every concentrate, and strengthen the recovery of associated silver at the same time of producing major metallic minerals. Metallic minerals, including copper, lead, zinc, tin, sulfur and silver, can be fully recovered by adopting combined procedure of selective flotation and gravity concentration, and other associated components in the ore are also recovered comprehensively, so the technology indexes of various products obtained are excellent.

Copper-lead-zinc mixed ore in Tibet, China, is a complex and refractory polymetallic ore resource; thus, ascertaining its mineralogical properties is very important for comprehensive recovery of valuable elements. In this work, the mineralogical properties of this copper-lead-zinc mixed ore have been characterized in detail following a multidisciplinary approach, including chemical, phase, x-ray diffraction (XRD), electron microprobe, and mineral liberation analyses. The results show that the raw ore contained 0.53% Cu, 1.29% Pb, and 0.54% Zn; the oxidation rates of copper, lead, and zinc were 40.21%, 79.31%, and 84.83%, respectively. The Au and Ag contents in the raw ore were 0.28 g/t and 23.6 g/t, which can be comprehensively utilized along with the recovery of copper, lead, and zinc. The gangue mainly contained SiO2, CaO, and Al2O3. Copper in the raw ore mainly existed in bornite, duftite, chalcopyrite, and chrysocolla; lead mainly existed in cerussite, duftite, and galena; zinc mainly existed in willemite, hemimorphite, and sphalerite. The complexity in the embedding and wrapping relationships, fine-grained dissemination, high oxidation, and considerable differences in the floatability of various minerals result in difficulties in recovering the target minerals using a single method. Based on the systematic mineralogical properties obtained, an integrated technology of “bulk flotation-oxidation roasting-hydrometallurgy” has been proposed to enrich and separate copper, lead, and zinc in the ore, providing new ideas for the comprehensive and efficient utilization of polymetallic mineral resources in Tibet.

The article discusses the results of technological studies on the concentration of polymetallic ore of the Chinarsay deposit. The results of studies of the material composition and flotation concentration options for technological samples of ore from the Chinarsay deposit are presented. The results of studying the material composition of ore based on spectral, chemical and rational analysis are presented. It has been established that industrially valuable ore components are lead, zinc and copper, the contents of which are given. It was shown that ore minerals are in close intergrowth with non-metallic ones - quartz, sericite, chlorite, carbonate, etc. It is noted that the studies were carried out in two directions: collective flotation of all ore minerals with further selection of the collective concentrate into lead, zinc, copper and pyrite concentrates and direct collective selective flotation to produce sequentially lead-copper, zinc and pyrite concentrates. As a result of enrichment, lead, zinc and copper concentrates are selected that meet the production requirements.

Composite Samples

A double reversal trial with three, 4-week periods was used to determine the effect on milk quality of feeding dehydrated poultry waste to lactating dairy cows. Fifteen cows were fed a control ration for 4 weeks (Period 1), followed by an experimental ration containing dehydrated poultry waste for 4 weeks (Period 2), and then by the control ration for 4 weeks (Period 3). Milk was collected daily and scored by five judges using the ADSA milk flavor scoring guide. Milk compsition (fat, protein, lactose, and solids-not-fat) was determined on alternate days. During Periods 2 and 3 weekly composite samples were collected to determine concentrations of cadmium, copper, lead, zinc, and tocopherol. No significant differences were found in any of the milk quality factors studied.
