In this study, the aim is to beneficiate magnesite slimes by flotation. In order to achieve flotation for −38 μm magnesite wastes effectively, ultrasonic treatment was utilized simultaneously and as a pre-treatment technique. The results of ultrasonic treatment for magnesite flotation were compared to the results of conventional flotation.

South Africa: Clean coal a viable option due to latest advances in fine-coal beneficiation. 12 November 2021. The shift to mechanised mining in the coal industry has had the side-effect of an excessive quantity of fines being produced, which often means that the thickeners deployed in minerals-processing circuits are undersized and cannot cope.
The beneficiation of iron ore slimes produced from washing plants and tailing ponds of Kiruburu mines was studied using wet high-intensity magnetic separators (WHIMS) followed by classification in hydro-cyclone whereby a concentrate assaying 63 % Fe and 3.3 % alumina was produced with an overall iron recovery of 56 %. Though multi …
The beneficiation of iron ore fines and slimes has not only received attention in India but also in many iron-producing countries in the world due to the fast …
Present investigation includes the magnetizing roasting of low-grade iron ore fines followed by grinding and beneficiation using magnetic separation. The hematite iron ore used in the investigation contains 53.17% T Fe, 10.7% SiO2, and 4.5% Al2O3. Powdered bituminous coal of 210 μm size with an ash content of 12.5% and fixed carbon …
ABSTRACT. A typical high-alumina containing iron ore slime from the eastern Indian sector containing 58.13% Fe, 6.48% SiO 2, 4.9% Al 2 O 3, and 5.35% LOI, have been evaluated to find out whether grinding of the slimes will be beneficial or not for upgrading the slime to generate pellet-grade concentrate with >64% Fe.Liberation …
Beneficiation is a process where ore is reduced in size and valuable minerals are separated from the gangue minerals. Separation of valuable minerals …
The beneficiation potentials of two Indian iron ore slime samples by flotation technique using both cationic and anionic collectors are investigated. The direct and reverse flotation of slimes ...
Beneficiation of alumina rich iron ore slimes is a major challenge for the Indian iron ore industry. High alumina is deleterious for the performance of both blast furnace as well as sintering plants.
The beneficiation potential of the iron ore slimes produced from the washing plants and tailing ponds of Kiriburu mines assaying up to 60% Fe, 3.34% SiO2, and 2.93% Al2O3 is analyzed.
Beneficiation of iron ore slimes has been studied. Three different iron ore slimes from Chitradurga, filling and Ukraine have been characterized in detail. The slime samples have ... the slimes are either dumped as stocks at the mine or permanently lost due to lack of proper beneficiation facilities. However it is reported in the literature ...
