In addition, the cost of such equipment that will process one hundred cubic yards of ore per hour exceeds half a million dollars
Furthermore, due to the heavy weight as well as the large size, such conventional equipment can only be transported to locations with good road or rail traffic

Abstract

A machine is employed for recovering heavy metals and precious or semi precious minerals, such as gold, copper, lead, diamonds, and garnets from placer, or hard rock ore. The machine employs a cylindrical, annular outer drum mounted for rotation at an inclination to the horizontal and including at least one spiral vane extending the length of its inner surface. A cylindrical, annular inner barrel is mounted within the drum and has an upper fragmentation section, an intermediate screened section, and a lower discharge section. A spray of water is directed into the inner barrel and a water spray bar is located in the annulus between the inner barrel and the outer drum. A fine sluice box is located to receive under one-quarter material input from a side trommel and a coarse sluice box located to receive discharge from the side trommel and discharge from the fine sluice box. The sluice box includes a plurality of landings, matting and screens upon which heavy materials, such as gold or precious stones, collect.

Description

technical field [0001] The present invention relates to methods and machines for recovering heavy materials such as gold, copper, lead and precious or semi-precious stones from placer (or hard rock ore). Background technique [0002] Many different installations have been constructed for the purpose of extracting heavy materials such as gold and other heavy metals and minerals from placer or hard rock ores. A very significant problem with conventional recovery plants used to recover gold or minerals from placer or hard rock ores is the inability of the equipment used to separate and recover very fine particles of valuable material and / or from placer or hard rock laden ores Or to separate precious particles with a slightly higher specific gravity than non-precious materials. Consequently, much of the valuable material processed through conventional recycling systems is not separated from the ore, but is instead discarded with the tailings. More specifically, conventional pl...
