Whilst the use of a shaking table was unsuccessful, a pilot Jones wet high intensity magnetic separator (WHIMS) proved to be more promising. In the latter case, testwork was conducted on an 'as-received' sample from the concentrator, i.e. that did not undergo any feed preparation, and another that was deslimed at 25 µm by wet …

3 Then, the concentrate enters a shaking table. Because the concentrate still has a little sand, using a shaking table can effectively separate sand from the gold. 2. Shaking Table for chromite The Cr 2 O 3 content in a certain lean chromite ore in Zimbabwe is only 8.19%. FTM Machinery has researched the beneficiation technology and equipment ...

Chrome ore gravity mining equipment includes the jig separator, shaking table, spiral classifier, centrifugal concentrator, and spiral chute. A weak or high-intensity magnetic separator is sometimes used to further improve the chromium concentrate grade and the chromium-iron ratio.

upgrade the low-grade chromite ore using different physi-cal beneficiation techniques for production of ferrochrome/ charge chrome. Gravity method like tabling was used by many workers to pre-concentrate chromite ore [6–19]. Nafziger [20] while reviewing the beneficiation of low-grade chromite ores from the world over opined that

The hydrosizer feed in the studied circuit (Fig. 1) is the middle product of the shaking tables with an average Cr 2 O 3 grade of 17%. The feed is classified based on the specific gravity and the liberation degree of particles. Outputs of spigots 1 and 2 are introduced to two separate spirals, and the output of spigot 3 is introduced to a shaking …

Comparison of SEM images of particles (in group and single magnified) in the (a) concentrate and (b) tailing products for coarse shaking table at coarse sized fraction (Â100) and (Â750). Figures ...

Introduction : Shaking table is physical ore processing equipment that utilizes the asymmetric reciprocating motion of bed to realize the heavy and light minerals separation. Product Use : It is mainly used for concentrate separating precious metals and rare metals with the diameter of 0.02-2mm, like Au, Ag, TaNb, Sn, etc.

With most high-quality tungsten ores being exhausted, the enhancement of low-grade scheelite concentrates processing has attracted a great deal of attention. The objective of this study is to develop a method to maximize the recovery tungsten and molybdenum from a low-grade scheelite via a new acid leaching process followed by …

This paper presents the results of an investigation on the concentration of a low-grade (30% to 35% Cr 2O 3) chromite ore from Chickay Mine, East of Sudan, using a shaking table. The studied ...

The MCHR is also processed separately to concentrate chromite in the MCHR-Chrome plant (or Chrome Washing Plant, CWP), with both concentrator plants employing spiral gravity concentrators. ... The …

From roughing and scavenging spiral groups, ~85% of chromite could be obtained prior to the shaking table concentration, and this led to a minimum increase of 20% in the total …

Sub-grade chromite ore with Cr2O3 of about 38.5% of Sukinda region of India, can be upgraded to a marketable chrome concentrate of 53–54% Cr2O3 with a recovery of about 58–60% and tailing loss of around 14–16.39% of Cr2O3, by using wet shaking tables in the circuit (Banerjee et al., 2005).

A three layer feed forward neural network (3:3–11–2:2) as shown in Fig. 2 has been developed for predicting the recovery and grade of the concentrate fraction of wet shaking table by using the three operating parameters like wash water flow rate (L/min), deck tilt Angle (degree), slurry feed rate (L/h) etc. The MLP architecture obtained has ...

Shaking tables find extensive use in concentrating gold. It is also used in the recovery of tin and tungsten minerals. These devices are often used downstream of other gravity concentration equipments such as spirals, Reicherts cone, jigs and centrifugal gravity concentrators for final cleaning prior to refining or sale of product.
