2. Spiral concentration with a view to produce low ash concentrate and high-yield middling with rejectable tailings (Test 2 as shown in Table 4). Further processing of the middling in a rougher-scavenger scheme. The spiral test results show that Scheme 1 produced a clean coal with 19.6% ash at 50% overall yield.

Low grade Iron Ore Beneficiation and the Process of Jigging ...

The reasons for choosing jigging for the iron ore beneficiation over other processes include (i) relatively easy separation (ii) beneficial trade-off between operating cost and reduced yield relative to dense medium processes (iii) ability to treat ores requiring cut densities higher than a density of 4.0 and (iv) physical characteristics of ...

DSO gravity separation Iron ore iron ore beneficiation magnetic separation Beneficiation of Iron Ores. Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron hematite) or Fe3O4 (72 % iron. magnetite).

A Review of Spiral Technology for Fine Gravity Beneficiation

The benefits of using the FM1 spiral for the treatment of fine grained silica sand tin tailings iron ore and copper were also investigated (Richards et al 2000). Other potential applications for the use of fine spiral technology include operations that currently grind their feed material to 80% passing 75µm to achieve satisfactory liberation.
