Hard rock hematite deposits often require a combination of milling, screening and on occasion, fine classifiion to prepare a finely sized (), liberated feed for beneficiation by gravity separation. This is typically followed by regrinding of the tailings to liberate more hematite for further iron unit recovery by magnetic separation.

The mining method used at the Tanami is longhole open stoping with paste or rock backfill, using a % mine recovery factor and a stope dilution factor that varies according to geotechnical recommendations (7% to 20%). Mine development is drilled using twin boom electric hydraulic jumbos. The jumbos are also used to install ground support.

They are perfectly suited for the secure recovery of gravity recoverable gold (GRG) and other heavy metals and minerals from both alluvial and hardrock plants. Batch Knelsons are available with a variety of concentrating cone designs and with centrifugal fields of up to 200g, to provide wide choices to suit different site and machine feed conditions.

 · Many of the products we use every day would not exist without the industrial minerals that are mined and processed. Vortex is aware of the importance of this industry and, as such, manufactures equipment to handle this vast array of materials.

 · Why the mining mineral industries choose Vortex: Experience – Vortex has been engineering and manufacturing gates, diverters and loading spouts for the mining and mineral industries for decades. Because appliion parameters in mining and minerals greatly vary, proper modifiions to standard valves is the key to getting the most out of your components.

For example, one miner improved his recovery from 40% to 70% simply by screening his feed from 8mm to 2mm. No gold was lost, because his largest gold was around .5mm. The iCON method will improve your process by screening your feed to the proper size.

EXTRACTEC Heavy Particle Concentration (HPC) technology enables costeffective gravity separation of minerals of differing densities without the use of chemicals. Based on our revolutionary patented transverse spiral concentrator belt and benefiting from almost 20 years of development experience, the system boasts fine gold recovery rates of 95%98% down to 50microns.

However, the specific gravity or unit weight of waste rock from the mining of iron ore and taconite will be considerably higher than that of conventional aggregates. The specific gravity of waste rock can be expected to range from to for most rock types and from to for waste rock from iron ore and taconite minings. Mill Tailings

A rocking motion provides the water movement needed for the gravity separation of gold in placer material. Hard rock mining Hard rock gold mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the world's gold. Sometimes openpit mining is used, such as at the Fort Knox Mine in central Alaska.
