“…Efforts Table 3 Physical and chemical properties of cassiterite (Blackburn and Dennen, 1988 Characteristically found in high-temperature hydrothermal veins or contact metamorphic deposits genetically related to quartzose igneous rocks. Also noted in pegmatites and as an accessory mineral in acid igneous rocks are made to recover these lost values using state of the art fine gravity machines such as Bartles Mozley separator (BMS), Bartles cross belt concentrator (CBC) and more recent Mozley multi-gravity separator (MGS) and Falcon Ultra-Fine centrifugal concentrator (Burt, 1984(Burt, , 1988Mozley and Childs, 1992). However, many plants consider flotation of tin using specific collectors because of the advantages like higher tin selectivity and recovery (Foo et al, 1983).…”

“…These enhanced gravity concentrators make use of centrifugal or other additional forces to increase the separation efficiency. Particle size plays a major role in gravity concentration (Burt, 1988); the separation efficiency is very high for coarse particles while it drops down considerably for fine sizes. The efficiency of different gravity concentrators treating tin ores has been investigated by many researchers (Falcon, 1982;Burt, 1984Burt, , 1988Turner and Hallewell, 1993), and it is reported that advanced gravity concentrators could recover particle size down to 3 lm.…”

Prolonged development of ore deposits, ore beneficiation and metallurgical smelting of concentrates result in the accumulation of wastes, forming large-scale dumps and sludge ponds negatively affecting the environment and human health. The creation and introduction of industrial waste treatment technologies will make it possible to dispose of them with the production of valuable commercial products and improve the environmental situation. In a research article on chemical beneficiation with the subsequent gravitational beneficiation of chrome-containing slurry tailings of Donskoy Ore-Mining and Beneficiation Plant (DOMBP), which processes chrome ore of the Kempirsay deposit in the Republic of Kazakhstan, Aktobe region, having considerable stocks of such waste is presented. The chromium-containing slurry tailings were heat-treated at 1100 °C, sintered with ammonium sulfate, water and sulfuric acid in a defined ratio at 300 °C, and then the resulting sinter was leached with water at 90 °C. The cake was washed to separate the liquid part from the solid part. The solid precipitate is the chromium-containing cake, which is upgraded by gravity concentration to a grade concentrate for ferroalloy production. When the solution is evaporated, magnesium sulfate with ammonium sulfate forms the Tutton’s salt ammoshenite. High-throughput chromium oxide extraction of 93.9% was achieved as a result of the research, and three products were obtained: (1) standard chromium concentrate with 49.48% Cr2O3 content, (2) ammoshenite used as a nitrogen–magnesium fertilizer and (3) forsterite, which is concentrated in gravity concentration tailings and can be used in the production of refractory minerals.

Recent advances m thc design of fine gravity concentrators and high gradient magnetic separation devices have ted to signilicant improvements in the recovery of tungsten values in fine and ultrafine size range. Amongst the more promising techniques of fine particle~ processing, encouraging results are reported on froth flotation, shear flocculauon and spherical agglomeration of tungsten ore slimes. Development of highly selective reagents such as alkyl hydroxamates, phosphonie acid derivatives and alkylated nitrosonapthols is vital for enhancing separation efliciencies in the shmes size range. Froth flotation of Indian tungsten ore slimes [partlcularly at Deganal using appropriate reagent combinations appears promising and need~ to be examined in greater detail.
