River sand ore separator

Abstract

The invention pertains to the field of machinery equipment, in particular to a river sand dressing machine which comprises a water washing ore dressing plant, an ore separating device and a power device (20), wherein, the water washing ore dressing plant and the ore separating device are respectively connected with the power device (20); the water washing ore dressing plant comprises a transmission device and a slewing gear which take a gold adsorbing blanket (5) as a transmission belt; the ore separating device comprises a separation slot (8) and a separation tray (14); one end of the water washing ore dressing plant is correspondingly connected with an inlet of a guide slot or a duct (7); the other end of the guide slot or the duct (7) is connected with the ore separating device by the separation slot (8); the horizontal bottom of the separation slot (8) is provided with a mercury separation slot (12); the surface of mercury is lower than the bottom surface of the slot; the separation tray (14) is arranged above a slot surface at one end of the separation slot (8); a bottom surface at the terminal of the end of the slot is provided with a slot port; the other side in the separation tray (14) corresponding to the slot port is provided with a separation magnet (15). The river sand dressing machine has compact structure and reasonable layout and makes full use of the adsorptionand protection effects of the gold adsorbing blanket and the alluvial gold and ore separating effect of the mercury; the discharge amount of the mercury is small and the mercury can be recycled.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, in particular to a river sand concentrator used for pottering gold sand and iron ore from river sand. Background technique [0002] River sand gold pottery has a long history, and there are various types of gold pottery equipment, such as large gold dredgers, spiral concentrators, etc. Most of the existing technologies use mercury separation method on the premise of overcoming mercury pollution, which is widely used because of its high efficiency, especially It is a low-pollution gold separation equipment that is very popular, such as the publication number: CN2316322, named "Sand Gold Homogenization Machine", which is mainly composed of a conical separator with a built-in coil and an amalgamator with a flat bed. The coil is made of There is a coarse material outlet, and the sand material is stratified in the conical separator along the spiral motion of the coil, and the purified fine material...

AI Technical Summary

Problems solved by technology

This technology has indeed made some progress compared to the traditional manual sand washing pottery gold, but the existing technology needs to be further improved, especially for gold sand mines rich in gold sand and iron ore, a small-scale automatic washing machine with a relatively high degree of automation has been designed. The river sand concentrator is particularly necessary
