Experimentation. Artificially mixed slurries of clay, pure magnetite and quartz (1 kg) were fed into the Knelson concentrator at a solid rate of 200 g/min to evaluate the effect of clays (bentonite or kaolin) on the separation of magnetite. The feed slurry contained 10% magnetite, different amount of clays (0, 5%, 10% or 15%) and quartz.
The Falcon Ultra-Fine (UF) Concentrator is designed specifically to process very fine particle sizes. It lacks the fluidizing water used in other centrifugal concentrators; instead relying on the geometry of the bowl walls to retain the high specific gravity material (Lins et al., 1992).

Ore blending is an essential step in the daily production of the concentrator. A good ore blending scheme can improve grinding production workload, reasonably allocate the amount of ore into flotation, gravity separation, etc., and improve the concentrator's production efficiency and economic efficiency [ 20 ].
The separation results indicated that the operating parameters have important influences on the performance of the concentrator, such as feed pressure, water inlet pressure, concentrating rings in separation cylinder, feed concentration, etc. ...

ore stockpiles from 2021. In addition, improvements in concentrator performance allowed more ore to be processed and, as a result, less ore was stockpiled The consequent impact on Mogalakwena's unit cost was an 18% increase to R18,522 per platinum ounce. Excluding the impact of the lower ore capitalisation and increased waste …

The concentrator is expected to operate at reduced rates until the third quarter, with Rio Tinto planning to truck ore while it sources replacement motors for the conveyor. The miner kept copper unit-cost guidance unchanged. At the Rincon lithium project in Argentina, development of a lithium-carbonate starter plant is ongoing, the …
11 hours agoThe concentrator is expected to operate at reduced rates until the third quarter of 2023. Escondida mined copper production was 6% higher than the first quarter of 2022 due to 10% higher throughput, which returned to normal levels after the corresponding quarter in 2022 included impacts from the COVID-19 pandemic and extended plant …
Concentrator. In the processing stage, the mined material is transformed into usable raw material. For iron ore this involves crushing the ore and then concentrating it in different …
concentrator performance. The case studies have been limited to UG2 concentrators due to the added complexity in the UG2 concentrator design and more stringent concentrate specifications. The UG2 Reef The UG-2 ore is a platinum-bearing chromitite ore that contributes a growing proportion of the platinum group
A concentrator can assess its energy cost performance by tracking specific energy use. The CEEC specific energy (tonnes intensity) curve can be used to benchmark comminution in a concentrator against other operations, and to compare the present concentrator against its past and future self, to determine if it is improving.
The concentrator has two processing lines. In 2018, Bystrinsky GOK started pre-commissioning of the processing lines, and in 2019 the concentrator was commissioned. In 2019, it processed 7.5 mln t of ore (2018: 3.8 mln t). The increase was due to scheduled ramp-up to design capacity.
The world's second-biggest miner by market value on Thursday said it shipped 82.5 million metric tons of iron ore from its mines in Australia's Pilbara region in the three months through March, up ...
5 minutes agoThe strong performance in iron ore was partially offset by a downgrade to copper production guidance because of technical problems at Rio's American (Kennecott) copper mines and confirmation that severe cost inflation was hurting the viability of its new lithium asset in Argentina. ... The concentrator is expected to operate at reduced rates ...
Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock.
The PGM grade of the feed to the UG2 concentrators typically varies from 2.0 g/t to 5.5 g/t. The feed grade is affected by the stoping height in the mine, how much of the hangingwall and footwall is included in the mining cut, and the presence of gangue partitions between the chromitite seams.
Apatite is the main source of phosphorous for the making of chemical fertilizers. While apatite is usually recovered from phosphate orebodies as the primary product of a mining exploitation, this paper documents the approach taken to produce a phosphate concentrate as a secondary product from the tailings of a niobium ore …

Bulk ore sensing and sorting enables the preconcentration of the concentrator feed while simultaneously improving its consistency. It sets a foundation for better performance in all subsequent operations delivering dividends by: Increasing resource utilization. Adding throughput with no plant expansion.
Higher energy use resulting from deteriorating concentrator operation (e.g. poor classifier performance) may make the mine economically unviable and should be arrested. New Gold New Afton (BC, Canada) is an example of an operation that installed additional grinding power, a 3000 HP Vertimill in a tertiary grinding duty, to reduce grind size and ...
