Flotation Cells

The flotation plant will treat the slimes from three existing dense media modules originally built by Zenith. The plant will make use of flotation cells that have been developed by Zenith.

Flotation cells are the widely used ore processing plants. Zenith flotation cells are featured with high quality, compact in size and low consumption.

Flotation Cells Overview

The Newly-designed flotation cells series retains the rugged aeration mechanism that has been proven in thousands of installations worldwide. Its massive cast-iron bearing housing maintains accurate shaft alignment under all loads and moments, ensuring long service life. Induced air flow provides sufficient aeration, mechanical simplicity and capital economy.

Zenith and Rio Tinto recently commissioned what the world’s largest operating flotation cells. WEMCO mechanisms are being utilized in flotation cells universal tanks which currently range in capacity sizes from 300m³ to 350m³. Zenith is currently installing 26 of the WEMCO 300 m³ flotation for Antofagasta Mineral’s Esperanza  plant in Chile, which will be the largest installation of its kind in the world.

Flotation Cells Application

Zenith can and has supplied the Bateman mechanism for retrofitting to other flotation cells in order to improve flotation performance and recoveries.

Zenith has developed a range of custom engineered solutions for various plants, and this willingness to partner with customers to incorporate novel design features to meet specific process design requirements has led to Zenith’s success with the Bateman range of flotation cells.

Flotation Cells Working principle

After mixing slime and pharmaceutical into the slot to the first flotation tank room below, the impeller rotation, the formation of negative pressure in the wheel cavity, making the tank bottom and slot in the next slurry by the impeller and the suction suction into the mixing zone, but also makes the air along the guide sleeve into the gas mixing zone, pulp, mixed air and agents here. In the impeller centrifugal force, a mixture of pulp into the mineralized zone, the formation of air bubbles and was crushed, and full access to the coal particles, the formation of mineralized bubbles and turbulence in the stator plate under the action of uniformly distributed in the tank section, and move up into the separation zone, a bubble-rich layer by scraping foam body discharge, the formation of coal bubble.

Mineralization above the bottom of the coal particles will not cycle through the suction hole and once again mixed, mineralization and separation. Impeller tank bottom is not part of the pulp, the pulp through the buried mine in the box under the slot into the second chamber, the first room to complete the entire process, into the third room, Single flotation machine again and again, through the pulp After the last room the final tailings discharged into the tailings box. Single flotation machine works.

Flotation Cells Project

Roca's Foremore project is located in one of the most active mining and exploration areas in British Columbia — the Eskay/Iskut Camp in the northwest region of the province. This camp includes Barrick Gold's legendary Eskay Creek Mine, Cominco's historic Snip Mine and NovaGold and Teck Cominco’s Galore Creek project.

Foremore was the focus of exploration conducted by Cominco Ltd. between 1989 and 1996. Despite the abundance of several mineralized boulder fields Cominco failed to locate a source of the base and precious-metals mineralization.

Roca's exploration crews have discovered numerous showings and mineralized zones in outcrop. The Company plans further exploration work at Foremore in 2007/2008.
