Highlights A rougher flotation simulator based on data from plant measurements is presented. Metallurgical characterisation was developed by mass balance and kinetic adjustments. The grinding effect was modeled using distributed flotation rates per size class. The simulator was calibrated using data from 130 m 3 cells in rougher …
In its essentials, a flotation cell must provide for two main functions. First, it must supply air adequate in quantity and quality for satisfactory process kinetics. Air quantity can be defined on the basis of the narrow range provided in major U. S. commercial cells, for escape velocity, which averages near 1.2 m/min (4 ft /min).

The simulation of closed circuit grinding with flash flotation requires the ball mill, the hydrocyclone and the flash cell to all reach steady state, as they all influence …
The tests were performed in the first cell of the rougher 1 bank (#1 Rougher 1). The flotation cell was a Denver sub-A type (, Finland). Air was injected into the cells. The flotation gas rate was 5 L/min, which was determined by the suction of air into the pulp through the impeller at 1200 rpm. The total flotation time was 8 min.
Flotation Circuits. Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks. Rougher and scavenger banks are focused on recovery and thus provide maximum residence time. Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses.
The JKSimMet® ball mill model is also not constrained from a volumetric and residence time perspective. At increasing flow rates and higher recirculating loads the residence time of the slurry in the ball mill reduces. Transport through the mill charge is believed to become constrained, with
The field test of the 15-m 3 StackCell flotation cell was conducted at Rio Tinto's state-of-the-art tailings recovery demonstration plant located within Kennecott …
Unit Flash Cell flotation tests should be made before planning an installation. This will establish if the ore will respond to such treatment to advantage. A 100 lb. representative sample of the ball mill feed is sufficient for the unit cell flotation tests. Flotation in a Grinding Circuit. The simplest flotation circuit is a comparatively ...

A typical ball mill classification circuit is provided below, with independent (or manipulatable) variables represented in green and resulting dependent
The flotation process is performed in two stages – bulk sulfide flotation and selective copper flotation (Figure 1). The purpose of the bulk circuit is to assure high recovery of …
This study evaluated a large-scale copper concentrator to understand the constraints that limit throughput and grind size in a closed-circuit ball mill classification circuit. The …
The flowsheet is shown in Figure 1, and Table 1 lists the number of cells, cell size, and effective volume of this circuit. This flo tation circuit comprised two rougher banks, a cleaner, and a scavenger. Each rougher bank contained four cells. The scavenger and cleaner were composed of four cells. The floated product of cleaner 1 bank was the ...
The flotation process and related flotation cells are widely used for treating metallic and nonmetallic ores and in addition, it is receiving an ever widening application in other industries. A greater tonnage of ore is treated by flotation than by any other single process. Practically all the metallic minerals are being recovered by the flotation …
The ore is mined from an open pit, crushed, and fed to ten ball mills. The concentrator is divided into two parallel comminution-flotation sections, so that five ball mills feed each flotation section. Both sections consist of three bulk copper and molybdenum rougher flotation lines, and the rougher concentrate is transferred to a …
