By ALICOCO’s type F spiral in rougher and type H spiral in scavenger to processing scheelite tailings, it has reduced the tungsten grade of the tailings from 0.12% to 0.018%, and the tungsten concentrate recovery rate has reached 81.68%, exceeding the recovery rate of the flotation process.

In South Africa, chromite recycle from platinum tailings with a particle size of -0.038mm,could up grade the chromite till 48% and platinum was also enriched to 2 ppm+.

In a malachite (a type of copper oxide ore) raw ore project in Zambia, aiming at the low-grade raw ore with a copper grade of only 0.4%, the spiral gravity separation process was adopted for pre-enrichment operation. This process achieves efficient separation by virtue of the difference in mineral density, effectively removes gangue impurities, and finally increases the copper grade of the roughly separated malachite concentrate to 5.2%.

The F8 spiral is used to process quartz sand, achieving a quartz sand concentrate yield of 80%, with impurities of iron and titanium <300ppm and a silicon content of 99.96%. It is also very effective in removing mica flakes from high-purity quartz sand.

The mainstream wet and dry desulfurization methods in power plants are post-combustion desulfurization, which has problems like large investment, high costs and difficult operation & maintenance. The innovative pre-combustion solution: wash coal with M5 type spiral machines for desulfurization after coal grinding, while recovering pyrite and ash; the calorific value of refined coal powder increases by 30%, and fly ash storage yards are reduced by 70%.
