2019910 A bulk flotation test was done in order to obtain a concentrate with recovered silver, lead and zinc bearing minerals. The recovery of silver from this test reached 67.81 and the final
20121127 silver. The overall tailings sample was found to contain 19.41 of pyrite, 2.02 of zinc, 0.69 lead, and 26.94 ppm of silver contents. INTRODUCTION Lead and zinc are important nonferrous minerals. In India major leadzinc deposits are located in Rajasthan state. Among the reserves in Rajasthan State, the deposit at RampuraAgucha in Bhilwara

A deepextened oxidized refractory leadzinc ore,from Cangyuan County Yunnan province and in which zinc is in form of hemimorphite,is taken as researches such as the direct flotation of Galena with butyl xanthate as collector,sulphidisation
201945 However, it is important to mention that, to the best of knowledge of the current papers authors, no study related to the recovery of silver from old mine tailings using flotation has yet been reported. Pioneer studies should be carried out in order to understand the reactional mechanisms affecting the flotation of silver bearing minerals.
20191029 The tailings from the molybdenum plant are the final copper concentrate typically greater than 30 copper. Following molybdenum rougher flotation and several stages of cleaning, a final molybdenum concentrate is produced. The final molybdenum concentrate is typically greater than 55. LeadZinc Ore. Lead and zinc often occur in the same ore.
2015910 A bulk flotation test was done in order to obtain a concentrate with recovered silver, lead and zinc bearing minerals. The recovery of silver from this test reached 67.81 and the final concentrate grade assayed Ag 550 gt with insignificant amounts of lead and zinc. A significant amount of pyrite was floated together with the valuable minerals.
