The Blue Bowl can recover Gold as fine as talcum powder, so give it a try -- the Blue Bowl Gold Concentrator system is pretty simple to use and delivers outstanding results! NOTE: To save on batteries, the easiest way to run a 12 volt pump from 110 volt AC is to buy an inexpensive battery charger like you would use to charge a car battery.
Mineral Spiral Concentrators: Multotec spiral concentrators segregate iron ore, chrome, mineral sands and other high-density mineral particles in sizes of less than 1.5 to 0.04 mm. Multotec's HX3, HX5 and SC mineral spiral concentrator ranges are comprised of modular housing frames consisting of two spiral assemblies.
Multotec mineral spiral concentrators allow for separation of fine heavy minerals in the size range 1.5 mm to 0.04 mm. Multotec HX3 and HX5 mineral spiral concentrators are used for chrome and iron ore, while the SC range is typically used for gold, copper, iron ore and mineral sands and other high density minerals.. HX3 and HX5 Mineral Spiral Concentrator features:
The sulfur rejection values achieved were superior to those were achieved by a spiral concentrator and a flotation column. The metallurgic performance for the – 37 µm fraction of all coal samples was minor due to …

It has now become almost an essential unit operation in any gold processing plant to assess the gravity recoverable gold content in the ore as well as to recover fine free gold from the grinding circuit. Knelson Concentrator (KC) first introduced to the hard rock milling industry there-by providing gold recovery by handling a maximum feed size ...
The use of gravity concentration is, and has always been, the conventional primary method for gold recovery from alluvial deposits. The development of high capacity cone concentrators and metallurgically efficient wash-waterless spiral separators has had some impact in the technology for alluvial gold processing, but perhaps more significantly has led to the relatively recent use …
Spiral concentrators are simple low energy consuming devices that separate minerals mainly on the basis of density. Spirals are widely used in mineral processing as a method for preconcentration and ... Spirals have a wide application, they are used in iron ore processing, coal, gold, chromites, mineral sands, glass sands, and in soil cleaning.
The northern U. S. iron ore ranges account for the second largest group application of Humphreys spiral concentrators. On the iron ore ranges there are 1712 spirals, or 18.2 pct of all spirals manufactured to the end of …

1. Introduction. Spiral concentrators are gravity based separation devices used for the preparation of coal, iron and other heavy minerals ores (Wills, 1992).The classification of the particles in spirals is based on the combination of gravity, centrifuge, drag and Bagnold forces (Atasoy and Spottiswood, 1995, Burt, 1984, Bouchard, 2001).The spirals operate on both …

The spiral concentrator is suitable for sorting fine iron ore, copper ore, chromite, aluminum ore, pyrrhotite, hematite, tungsten ore, tin ore, gold ore, and other non-ferrous metals and rare metals with different specific gravity. The spiral concentrators produced by FTM are divided into four types: DL2000, DL1500, LL1200 and LL900.
The results of the linear circuit analyses should not be taken to imply that traditional multi-stage spiral circuits have no value. The primary advantage of these traditional circuits is that they provide an effective means for reducing the specific gravity cut-point (SG50) below that which may be achieved using a single-stage spiral.
