By emulating the phyllotaxis structure of natural plants, which has an efficient and stable light capture capability, a two-dimensional spiral grating is introduced on the surface of crystalline silicon solar cells to obtain both efficient and stable light absorption. Using the rigorous coupled wave analysis method, the absorption.

Spiral separators for gold are gravity concentrators and separate minerals of different specific gravity according to their relative movement in response to.
Outotec Spiral Concentrator. Get an effective, low-cost device for the gravity beneficiation of ores. Outotec spiral concentrators are used in most applications, particularly for concentrating low-grade ores. Manufactured from lightweight, corrosion and abrasion-resistant materials, our spirals require minimal maintenance and.
The spiral concentrator is considered as one of the most efficient and simple operating units for processing of minerals and coals. Because of its relative simplicity and high efficiency, it is widely used under a variety of circuit configurations. Since, their first-introduction by Humphreys in the 1940s, spirals have proved to be a.

The historical development of Reichert spirals is breifly reviewed prior to describing models developed specifically for the treatment of coal fines. Results obtained from laboratory tests and field trials of pre-production prototypes are presented. Comparisons are provided both between different tests and between test results.
Significant strides in the modelling of spiral concentrators have been made during the last couple of decades. Despite these . HOLLAND-BATT, A.B.
