Knelson Concentrators adopted and used these procedures to develop their KC-MOD*Pro circuit simulator, which allows accurate modelling of plant recovery on the basis of lab test results. GRG, EGRG and modelling now allow fully informed decisions about gravity processing to be made long before the casting of first concrete on a new plant.

the Knelson concentrate was tried but was unsuccessful due to the coarse nature of the concentrate and inefficient mixing vessels. Further gravity concentration methods were then employed, along with acid leaching to treat the Knelson concentrate. This is shown schematically in Figure 7. Jigs were installed to further concentrate the Knelson ...

Knelson™ and Falcon Concentrators Popularized Gravity Centrifuges. The development of fluidized gold centrifuges has a rich history, starting in Australia in the 1930's. However, the equipment was not popularized until the development of the Knelson™ and Falcon concentrators in the 1980's.. The Knelson™ concentrator consists of an inclined, …

Abstract In this study, modeling and optimization tests were conducted on enrichment of chromite ore by Knelson concentrator. For this purpose, the three-level Box–Behnken experimental design method was applied. The analysis of variance (ANOVA) was used at 95% confidence interval to test the significance of independent variables …

The motor power (%), solid feed rate (g/min) and air fluidising pressure (psi) were chosen as independent variables, with five levels (±β, ±1, 0 where β = 2 3/4 = 1.682) for each variable, with the response variable being the tungsten recovery for each size fraction. Because the controller of the Knelson Concentrator indicates the motor power …

Metallurgists operating Knelson Concentrators (KC) often rely on manufacturer's recommendations for selecting operating parameters, such as fluidising water flow rate and cycle time. Recent studies have shown that these parameters are not only dependent on the machine parameters but also on the feed characteristics, such as size distribution of the …
