Flotation of Gold and Gold-Bearing Ores ScienceDirect

Jan 01, 2016· 1. Background. The application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals (Weinig and Carpenter, 1937, Rabone, 1939, Richards and Locke, 1940, Taggart, 1945).

A review of the flotation of native gold and electrum

Sep 01, 2001· It is interesting to realize that the application of flotation to gold ores began, in a sense, in 1893 when, according to Hoover (1912, p. 22), British patent No. 24,939 was granted to H.L. Sulman for a process to prevent the loss of "float" gold in stamp battery milling of gold ores by adding substances (unspecified) which wetted the gold and

Silver Gold Recovery Flotation Process

The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver are of primary importance, the base-metal minerals, if present, being of little or no value. The first class

Sulphide Gold Ore Treatment by Leaching and Flotation Process

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an

Jameson cell Wikipedia

The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for

INTERPRETATION OF FLOTATION DATA FOR THE DESIGN

For a testwork laboratory treating a wide variety of ores, the most useful laboratory flotation machine is probably one with cells of 500, 1000 and 2000g capacities, with a different diameter impeller for each cell, with stainless steel or rubber-covered impellers, glass or plastic cell bodies, and requiring an outside source of low-pressure air.

In the mechanical flotation cells the feed can be introduced directly to the impeller zone from the side as in a Denver-style Sub A sub-aeration machine. A centrally located paddle-wheel type impeller generates a rotating pulp vortex which extends between two stationary elements: the sand-pipe located at the top of the cell, and the draft tube located at the bottom of the cell. The hydraulic
