This paper presents a new approach for flotation circuit design. Initially, it was proven numerically and analytically that in order to achieve the highest recovery in different circuit configurations, the best equipment must be placed at the beginning stage of the flotation circuits. The size of the entering particles and the types of streams including pulp and froth were considered as the bas...

effect of concentration parameters on recovery of zinc oxidized minerals from lead flotation tailings of dandy mineral processing plant in north-western iran was studied. a sulfidization-flotation method has been used on a laboratory scale to investigate the effect of various reagents such as sodium sulfide as sulfidizing agent, primary amine as collector, dispersants and flocculants with diffe...

It is possible to obtain good performance from a flotation plant but it has proved difficult to maintain such performance. Recovery rates on a flotation plant can be around 90% and often lower, making flotation one of the least efficient processes in the concentration path. Hence, over the last few decades much research and development has gone into the stabilization and optimization of flotati...

a simple, rapid and economic procedure was presented to remove lead(ii) from aqueous solution under the optimized conditions. it is based on the sorption of pb2+ ions from aqueous solutions onto limestone fines (ls), which is an inexpensive and widespread over the globe, followed by flotation with oleic acid (hol) surfactant. the different parameters (namely: solution ph, sorbent, surfactant an...

Sulfide lead resources are being depleted and the exploitation of carbonate lead deposits is now the main focus of lead mining. Cerussite, PbCO3, is majorly discarded to tailing damps because it is difficult to be processed by flotation in lead concentration units. This paper not only investigates the optimization of cerussite flotation, but it also proposes a model for predict...

Flotation is a common process in sulfide ore beneficiation. Due to the restrictions and lack of access to high-quality water sources for industrial purposes, recycled water plays an important role in the flotation processes. Due to the existence of various organic and inorganic substances in the process, water influences the flotation performance. In this work, the effect of accumulation of sul...

Bama is one of the major concentrating plant in Iran which treats nearly 1500 tons per day sulphidic lead and zinc ore. Large amount of oxidized ore exist in Bama which has been extracted along with sulphidic ore. The main objective of the present investigation was the up-grading of the ore from Goshfil which is the major deposit in Bama. The ore contained about 16% zinc as smithsonite, about 1...

A lead-zinc carbonate ore sample containing 2.5% Pb and 9.39% Zn was used in this research work. The sample was prepared from the Darreh-Zanjir mine located in the Yazd province (Iran). Influences of the influential factors on flotation of smithsonite and cerussite were investigated. Among the different parameters involved, dosages of the dispersant, depressants, sulfidizing agent, and collecto...
