That is to say the results obtained using other techniques with industrial gravity equipment namely jigs shaking tables spirals and centrifugal concentrators do not surpass those of HLS. Regarding grain-size intervals magnetic separation by Dry- and Wet-HIMS showed greater efficiency than HLS.
researches on the separation principles  while a few applications have been accomplished in processing of low-grade ochre. In this research dry and wet high-intensity magnetic separation methods were applied in processing of red ochre. 2. Materials and Methods 2.1. Low Grade Ore Characteristics
The wet shaking table was chosen to separate the materials. This is a process commonly used in mineral processing to concentrate ore with particle size range between 0.6 mm and 8.0 mm (Wills et al. 2005). The wet shaking table is quite a complex process and the equipment has several operating parameters that must be set for maximum efficiency.

Shaking table is the most widely used and most efficient gravity separation equipment for sorting fine ore. Shaking table beneficiation can be used as an independent beneficiation method or can be combined with jigs flotation machines magnetic separators centrifugal concentrators spiral chutes and other beneficiation equipment.

to +600 µm) and shaking table for fine particle fraction (-600 µm) led to better results compared to the case when only shaking table was used after de-sliming (-600 µm). Using one step jig machine for particles finer than 12 mm a tungsten ore specimen WO. 3. grade increased from 0.5% to 4.5% . Gravity separation by shaking table on the .
Gravity concentration can range from simple hand-panning for free gold recovery to larger batch testing with a Knelson concentrator or continuous concentration or cleaning using a laboratory jig and shaking table. Magnetic and electrostatic separation can be tested using a number of different laboratory units including wet and dry magnetic .
Experimental design technique is applied to optimize shaking table and dry high intensity magnetic separation processes on recovery of cassiterite from Igla Placer ore of Eastern Desert of Egypt.
This study aimed to evaluate the chromite recovery from shaking table tailings of Forumad plant by a dry high-intensity magnetic separation. The average feed grade of chromium trioxide (Cr 2 O 3) was 7.62% by XRF. Also different mineral phases were determined by XRD identifying the presence of Chrysotile Augite Albite Chlorite and Chromite.
