The extract the metal from ores, several physical and chemical methods are used. The method used depending upon chemical properties and nature of the ore from which it is to be extracted. It involves four main steps: 1. Crushing and grinding of the ore. 2. Concentration or dressing of the ore. 3. Reduction to free metal. 4. Purification or refining of the metal.

Flotation machine are mainly used in mineral ore dressing plants, selecting the valuable mine from gangue. It is applicable for the separation of numerous of mineral ores, such as fluorite and talc, gold ore, copper ore, iron ore and zinc ore and so on.

Providing a good solution for you is our goal, our price is also competitive.

VSI5X Series Crusher ( Sand Making Machine ) is suitable for secondary crushing and different hardness ores and rockets, especially for the secondary crushing of the high hardness materials such as iron ore, non-ferrous metal, emery, bauxite, quartz sand, brown fused alumina, pearlite, basalt etc.

SBM belt conveyor is widely used for transferring lump materials or manufactured products in mining, construction, metallurgical industries and other industries, for example, when coal, mineral ores, rock stones are crushed and some other products are packaged, our belt conveyors can be used to transport them.

Cone crusher is applied to cement mill, mining, building construction, road &bridge construction, railway construction and metallurgy and some other industries. Materials like iron ore, granite, limestone, quartzite, sandstone, cobblestone and some others are easily crushed by cone crusher.

The pioneers in progressive mine rehabilitation is one of the greatest assets in departmentalizing mining stereotypes. Environmentally friendly procedures and more and more miscellaneous ecosystems are becoming the standard as companies regard local ecosystem rehabilitation as a part of the on-going mining process. To better understand these progressive rehab techniques, here are some words from Idemitsu Australia Resources Corporate Sustainability and Environment Manager Dr. Jan Green and Parsons Brinckerhoff Team Manager, Alex Cockerill. "There's an increasing focus on establishing complex and diverse natural ecosystems as part of mine rehabilitation," she says. "With progressive rehab, it takes a much shorter time after the mine closes before the original flora and fauna can take over naturally." Her existing project is a 6- to 7-year-old mine that will sooner or later go back to a box gum woodland with white box gum trees. She explains that one of the biggest challenges is keeping up with the mining as it happens. A strict schedule of clearing between summer and autumn allows species, for example, to nest in the winter and raise young in the spring. Cockerill says the team salvages hollow logs and timber for the provision of supplementary fauna habitats within the rehabilitation, and collects the seeds of local species of plant from the adjoining forest for propagation in a nursery. By means of local species, it provides them a better chance of growing for the reason that the topsoil is recreated with greater accurateness. Sequentially, local fauna, from invertebrates to birds and mammals, are attracted to familiar landscapes. "With the progressive establishment of increasingly complex vegetation structure and diversity these ecosystems encourage more local species back onto the mine site," Cockerill explains. "It's then supported by biodiversity monitoring to target measurable performance criteria throughout the life of the mine and reh

The epic proportions of the illegal mining scam that was uncovered by the Karnataka Lokayukta in its 2011 report may actually have been just one act of a much larger, more complex and multi-layered drama. There is now new evidence to suggest that the Lokayukta's final report on illegal mining - a political game-changer that sent the powerful to jail and catalysed a regime change in the state - is just one part of the mining story. A six-month-long investigation by The Hindu, with help from whistleblowers in the Railways, the Karnataka Commercial Taxes Department and the CBI, points to losses to the State exchequer between January 2006 and December 2010 that are, at the very least, Rs. 1 lakh crore or eight times the estimated figure given in the Lokayukta report.

Vibrating Feeder is a kind of linear-direction feeding equipment, in the mineral ore &rocks processing plants, it can send materials to crusher evenly and continuously. At the same time, it can screen materials roughly, increasing the practical handling capacity of the whole production line.

SBM not only provides the main crushing equipments, such as various Crushers, Belt Conveyors, Feeders, but also the quality framing-members and unitized solutions. SBM's framing- member adopts advanced cutting, welding, sand blasting and anticorrosion treatment, which make sure everywhere of the crushing line is perfect, even a screw.

Usually construction recycling plants includes following machines: vibrating feeder, jaw crusher+ impact crusher, vibrating screen or portable crushing plant.

The ball mill is key equipment in grinding industry, especially in mineral ore dressing plants. It is suitable for grinding material with high hardness, such as the cement, the silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc. The shape of the final products is circular, the capacity and fineness also can be adjusted by adjusting the diameter of the ball.

Hammer crusher is mainly suitable for crushing various soft and medium-hard ore, whose compression strength is not higher than 320MPa, such as coal, salt, chalk, gypsum, blocks, limestone, glasses, and phosphate, etc. Hammer crusher designed by SBM fits for producing 0-3MM coarse powder products. This machine adopts theories of traditional crushing machines and grinding mills. It makes up the shortage of common mills, and it is the best choice to produce coarse powder at big capacity.

Both in rock stone crushing and mineral ore crushing industry, mobile crusher is becoming more and more popular. The mobile cone crusher will process concrete, kerbstone, marble, paving slabs, bricks, tiles, blocks, stone, porcelain, flint, gravestones, etc, under any condition and meet the requirements from our customers.
