2015-11-1 The yield of molybdenum-bearing copper concentrate was too low in each batch flotation to carry out the copper–molybdenum separation because of the low grade (0.90% Cu and 0.056% Mo) of the ore. Therefore, the molybdenum-bearing copper concentrates from different batches were blended together to obtain sufficient sample for copper–molybdenum separation.

2021-3-19 The concentrate products of copper, lead, and zinc can be obtained via flotation separation. The concentrate products of sulfur can be obtained only when the ore’s pyrite content is high. Gold and silver can be recovered from the concentrates of copper, lead, and zinc or from the products of pyrite. The goal of floating pyrite is not to recover

2017-6-5 Flotation of Chromite Gravity Concentrate. The amine flotation method was applied to chromite gravity concentrates prepared from Benbow-2 ore by a combined Humphrey’s spiral and table separation technique. The purpose of re-treating the gravity concentrate was to prepare a low-silica feed material for refractory testing.
