Copper and Molybdenum Flotation Circuit Copper / Molybdenum Flotation Circuit . Molybdenum (moly) is often produced as a byproduct of copper mining. Copper is used for electronics, construction, and metal alloys. Moly is mostly used to make metal alloys, and as a catalyst.
Flotation Machine,Copper Ore Flotation Machine,Flotation Cell,Froth Flotation machine is the equipment to complete the flotation process, which is also called flotation cell. It is widely used for the rough, fine and reverse flotation
The flotation circuit of the Sarcheshmeh copper mine, which processes 41 000 t day–1 of ore at 0· 9% Cu, consists of rougher, cleaning and re-cleaning stages. To study the stage recovery of copper, one of the eight identical flotation banks was selected for sampling. It was observed that 17% of copper goes to the tailings and
per day of copper and up to 27000 pounds of molybdenum per day. The ore goes through several stages of crushing and grinding on its way to the flotation plant. Upgraded concentrate from the bulk flotation process feeds the copper-molybdenum separation flotation circuit.
The copper flotation tailings are the feed to the sphalerite flotation circuit where the zinc minerals are floated as explained in the lead-zinc flotation section. Sphalerite is first activated with CuSO4 and floated typically at elevated pH for iron sulphide depression.
Laboratory flotation circuit The plant rougher flotation stage was approximated in the laboratory to enable a gold deportment study on the products to further investigate reasons for poor flotation of gold. The procedure is shown schematically in Figure 1. A Cominco stainless steel mill was used with 14.4 kg stainless steel rods.
CONCLUSIONS Colunm flotation teclmology has significantly contributed to the simplification of the copper flotation circuits, allowing a decrease in the number of units and the number of stages, while maintaining or bettering the overall circuit metallurgical performance.

"flotation circuit". The behavior of the entire process, therefore, depends on the configuration of the circuit, equipment design, and the chemical and physical nature of the pulp treated. It is for this reason that the preliminary design of the flotation circuit is
Given the measured copper and iron feed grades, this sub-model determines feed composition, considering various limiting conditions obtained from several mineralogical analyses of the ore treated in the flotation circuit. With respect to the copper feed grade, three cases are defined. When the copper grade is between the limits specified in Eq.
The texture of particles within a flotation cell play a pivotal role in both mineral recovery, and the grade, in the flotation concentrate. Theoretical curves can be generated based on particle mineralogy and texture to indicate the maximum grade-recovery possible for a given feed ore.
significantly affected copper recovery whilst pH was found to also significantly affect cobalt recovery. Keywords: flotation, process optimization, Taguchi orthogonal array, ANOVA. 1. Introduction Froth flotation is widely used for separating base metal sulphide minerals in complex ores. One of
Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash.
Estimated Water Requirements for the Conventional Flotation of Copper Ores . By Donald I. Bleiwas . Introduction . This report provides a perspective on the amount of water used by a conventional copper flotation plant, including the makeup water required to …
The zinc reporting to the bulk flotation tails feeds the zinc circuit which is operated as previously described in the lead-zinc flotation section. Which flotation scheme used in the differential copper-lead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate.

of mineral in the flotation circuit means the less likely the oxidation of the mineral surface. Case Study Sites The Mount Isa Mines Copper Concentrator and the Zinifex Century Zinc Concentrator were used to evaluate the benefits of the Jameson Cell at the head of the flotation circuit. A brief description of the operations is given below.
The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated. The tailing from the lead flotation circuit is the feed to the zinc circuit.
Copper processing example A high pH is important in copper ore processing to maximize this mineral's flotation properties. Most copper ore slurries tend to be acidic. Plants typically add lime to the slurry in the mill or floatation circuit, increasing its alkalinity. A typical copper operation contains many flotation …

Commercial copper production was declared on March 1, 2009, when copper concentrate inventory levels surpassed the 5,000 tonne shipping threshold. Increased zinc levels in the ore body, as it was continuously being mined, prompted the construction of a Cu/Zn separation circuit as extension of the previous flotation circuit.
