 — Pyrite in deionized water. Particle size P80 = 106 µm. pH = 5 fixed with H 2 SO 4 /NaOH. 1.5 L JK flotation cell. Without activation by copper, pyrite lowered its recovery with the three hydrophilic biopolymers. When the biopolymer concentration was 7 mg/L, DP-1775 and DP-1778 slightly depressed pyrite, but DP-1777 did not show depression.

 — Analysis of the adsorption capacity of the reagents on the mineral surfaces was based on the total organic carbon (TOC) content remaining in the slurry (Schumacher, 2002). A high TOC content in the slurry indicated a low adsorption capacity of the reagent on the mineral surface because the TOC content added to the flotation cell was constant.

 — The HydroFloat™ cell was indicated as a promising technology for recovering coarse particle fraction sizes by taking advantage of the fluidized-bed concept with plug …

grade of 24% copper could be achieved at acceptable recoveries. Incremental improvements in copper recovery achieved by 2011 through conversion of were conditioning cells to flotation cells in both roughing and first cleaning and increased cleaner capacity through the installation of a Jameson cell.

The No. 8 Batch Unit Flotation Cell has a capacity of 2.75 cu. ft. and will handle approxi­mately 50 pounds of solids per batch. The machine is equipped with a sloping bottom and ...

 — "The single most important method used for the recovery and upgrading of sulfide ores", that's how G. J. Jameson described the froth flotation process in 1992. And it's true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories …

Practical design considerations such as flotation time, type, number and size of flotation cells, and the means of froth transport are all important and appropriate test work can guide decisions on all these factors.

The REFLUX™ Flotation Cell (RFC™) operates at a magnitude far beyond the capacity of existing flotation devices, reducing the required installation footprint.

By late 1995 the Philex Mining Corporation copper concentrator had installed Jameson Cells throughout the circuit. (Harbort, Murphy, Budod, 1997). This operation was the first base metals operation to apply the ERM system. The project precipitated the development of much larger Jameson Cells and so a large increase in Jameson Cell circuit capacity.

 — Fig. 2 shows the P 80 of different mineral species in an ore for a major copper operation. These values vary significantly, with the P 80 of total solids, sulfide minerals, iron minerals, copper minerals and molybdenum are ∼ 200, 105, 125, 94 and 85, respectively. Flotation optimization of complex ores often requires a better understanding of the size …

 — The existing Section 1 bulk rougher lines consist of three parallel lines of 18 cells per line with a total flotation capacity of approx. 1529 m 3. Section 2 bulk rougher stage also consists of three parallel …

 — The scale-up procedure has four steps. Determine mineral rate constants, k, using the 50 mm column. Estimate from theory expected mixing conditions for chosen …

Jameson Cell has accurate scale-up reliability and is the real-word specification in any and all duties within a flotation circuit: rougher and scavenger duty; cleaner and cleaner scavenger duty. In fact, a single Jameson Cell has successfully replaced a traditional circuit of cells; and unlike other competing cells, it has no moving parts.

The size of flotation cells in the rougher-scavenger flotation should be as big as possible with the constraint that at least 7 cells is desirable in total to avoid short-circuiting losses. As few ...

The equipment indicated has been proven for long life and low maintenance, and to give superior results. ... Unit can be removed quickly while other cells are operating. Copper Cleaner Flotation.

In 2014, a 500 m3 cell went into operation at the Kevitsa Copper-Nickel concentrator in Finland, followed by two 630 m3 cells at the Buenavista del Cobre Cu-Mo concentrator in Mexico in 2018. These were the two largest cells in the world in operation at that time.

 — The Concorde Cell is a high-intensity pneumatic flotation cell dedicated to fines and ultrafines. Its development by Professor Graeme Jameson and later on by was driven by two considerations: a reduction in bubble size and an increase in the shear rate and energy dissipation rate increases the particle–bubble collision and attachment …
