A modal examination of the products produced by the copper flotation rougher-scavenger circuit reveal important information regarding the limits to theefficiency of the process, imposed by mineralogy, fragmentation and flotation capacity. Let8217s discusses various aspects of rougher flotation circuit performance and how to evaluate its results.

Typical minerals present in the rougher flotation concentrate and scavenger flotation concentrate streams.
Prior to compositing the individual downbank rougher and scavenger cell products, for modal analysis, the metal distribution by flotation cell products was determined.
It was apparent from this analysis that most of the lead, presumably as liberated galena in the ore, was recovered in the scavenger circuit. Therefore, it was decided to conduct the modal analyses on weighted composites of the rougher concentrate and scavenger concentrate streams.
Summary of the metallurgical performance of the copper rougher and scavenger circuits.
The recovery of liberated grains of chalcopyrite follows a typical pattern where about 75 of the liberated chalcopyrite is recovered into the rougher concentrate. The copper scavenger circuit essentially recovers the remainder of the liberated chalcopyrite.
The Flotation machine Flotation separator can be used for separating non-ferrous metals, ferrous metals, noble metals, non-metallic ores, and chemicals. The flotation machine can be used in roughing, scavenging, selection or reverse flotation.
The Flotation machine Flotation separator can be used for separating non-ferrous metals, ferrous metals, noble metals, non-metallic ores, and chemicals. The flotation machine can be used in roughing, scavenging, selection or reverse flotation. In the flotation process, after being mixed with additives, some qualified minerals float to the surface of the slurry and are scraped out while other minerals remain and are thus separated. We also provide flotation cells.
Impeller of SF flotation separator is composed of the dosed double section cones and it can produce strong smutty cycle downward. Its features are as follows.
Flotation Cell,FULIN MINING. Principle of operation . Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding a process known as comminution so that the various minerals exist as physically separate grains.This process is known as liberation.The particle sizes are typically less than 0.1 mm 100 181m, but sometimes sizes smaller than 7.
2 With three functions of air suction, slurry suction and flotation simultaneously being unique in flotation return circuit without need for any supplement and equipment, the circuit change is convenient for horizontal location.
3 The slurry cycle is rational the settlement of coarse sand can be reduced into full play.
4 The regulation is convenient to equip auto and electro-controlling arrangements for slutty level.
Column Flotation. Eriez Flotation is the world leader in column flotation technology with over 900 installations. Columns are used for floating well-liberated ores. Typically they produce higher grade and have lower power costs than conventional cells. Applications include. Roughers Scavengers Cleaners.
2 The impeller of the flotation machine begins to rotate negative pressure is formed, which makes the air and pulp at the bottom and middle part of the tank enter the mixing zone. The pulp, air and medicament are then mixed in the mixing zone.
3 As a result of the centrifugal force, the blended pulps are led to the mineralization area. The air is in full contact with the coal particle and forms mineralized bubbles which are then equally distributed to groove wall and removed upward to the separation region. These bubbles then gather as a foam layer and are discharged by the scraping tool. Finally, clean coal foam is produced by this flotation machine.
During the last six months, Metso has received orders to install over 50flotation cells in Spain and Portugal, ranging from small 15m units to large 300m cells. Metso will deliver flotation equipment to expansion projects by Almina, Somincor and other leading mining companies located on the Iberian Pyrite Belt as well as Saloro in Barruecopardo, western Spain. Metso RCS flotation equipment is designed to ensure higher recovery and throughput as well as to reduce maintenance and energy costs.
The Metso RCS flotation machine combines the benefits of circular cells with the unique features of the DV mechanism, creating the ideal conditions to maximize flotation. The new improved RCS flotation cell is an all-purpose flotation machine suitable for all flotation applications, such as roughing, cleaning and scavenging. Metso offers the full range of cell volumes required for modern ore processing plants, with cell sizes from 0.8m3 to 600m3.
From an initial installation in lead slimes cleaning the Jameson Cell is now in operation treating coal, nickel, zinc, copper, leached oxides, antimony and for removal of organics from electrolyte solution. Operations are conducted across a wide range of particle sizes and pulp densities, in cleaning, roughing, scavenging and flash flotation roles.
