Gold Flash Flotation with Whole Ore Cyanidation Leaching

FLOTATION and Cyanidation Leaching Circuit

GOLD CIRCUIT PROCESS FLOWSHEET DESCRIPTION: At the ball mill discharge, a Gold Flash Flotation Cell ahead of a cyanide circuit for the removal of concentrate for finer grinding or roasting, or for the removal of sulphides that are cyanicides (cyanide consumers) or for the removal of other interfering constituents. ORE TREATED: On ores where gold and […]

Coarse Flash Flotation Circuit

Coarse Flash Flotation Circuit

DESCRIPTION: A Unit Flash Flotation Cell in coarse concentration flotation circuit. This flowsheet is similar to our Coarse gravity concentration followed by flotation circuit. ORE TREATED: This flowsheet can be used on ores wherein the base metal minerals are freed at a coarse size. This is often seen on Pb Lead/Galena flotation located on the ball mill […]

Coarse Ball Mill Grinding >Gravity Gold & Flotation Recovery Circuit

Coarse GRAVITY concentration AND flotation

DESCRIPTION: A flowsheet of Coarse gravity concentration followed by flotation circuit. ORE TREATED: On ores wherein base metals or gold bearing pyrite free at a coarse size. ADVANTAGES: This flowsheet illustrates the application of a concentrating table in the ball mill classifier circuit, followed by flotation of the classifier overflow at a finer mesh. Where […]

Flotation of Cyanide Leaching Tailing

Flotation of Cyanide Tailing

DESCRIPTION: Flotation of cyanide tailing after a Merrill-Crowe gold recovery circuit. ORE TREATED: Where ore bodies at depth have become more refractory and flotation ahead of cvanidation would call for major and expensive mill alterations, the sulphide minerals containing the undissolved precious metals can be recovered by flotation and shipped to the smelter. In some […]

Flotation, Gravity and Tailings Cyanidation Leaching Circuit

Flotation_with_cyanidation_of_flotation_tailings

DESCRIPTION: Flotation with cyanidation of flotation tailings. This flowsheet has a gravity gold recovery embedded into the grinding circuit’s ball mill discharge. ORE TREATED: Ores containing both oxide and sulphide minerals with gold or silver, or those with cyanicides which must he removed before cyanidation. ADVANTAGES: This flowsheet makes possible the milling in one plant […]

Flotation & Cyanidation Leaching of Concentrate

CIRCUIT_cyanidation_of_flotation_concentrates_FLOWSHEET

DESCRIPTION: Flotation followed by cyanidation of flotation concentrates. In this flowsheet the flotation concentrates produced are reground and treated by cyanidation leaching. ORE TREATED: Sulphide ores wherein base metal values are negligible (such as pyrite) but with good gold and silver values, or in cases where increased returns can be secured from the marketing of […]

Flotation & Shaking Tables with Open Circuit Ball Mill

flotation and gravity shaker table circuit process flowsheet

DESCRIPTION: Flotation followed by shaker table concentration in open circuit grinding. ORE TREATED: When the mineral in an ore is freed at a coarse mesh, this flowsheet gives high recovery and high capacity. The practice is limited in scope, as on ores requiring fine grinding, closed circuit is preferable, and on ores wherein the gold is free, amalgamation […]

Closed Circuit Flotation with Regrinding Flowsheet

Regrinding and Flotation Flowsheet

DESCRIPTION: Regrinding of scavenger flotation concentrate middling OR flotation cleaner tailing and refloating the ground product in closed circuit cleaning. ORE TREATED: Flotation middling containing valuable mineral particles attached to the gangue particles and which can be freed by finer grinding. ADVANTAGES: Middling is designated as such because it contains material which lowers the grade of […]

Coarse Flotation with Gravity & Regrind Circuit

Coarse Flotation Process Flowsheet

DESCRIPTION: Coarse flotation followed by regrind of coarse rougher concentrate and selective flotation or cleaning. Coarse flotation tailings and reground rougher concentrate are processed over a shaking table for precious metals. ORE TREATED: Ores wherein the minerals can be freed from the gangue at a coarse mesh and subsequently separated from each other after finer grinding. […]

Sequential Selective Flotation Process Flowsheet

Simple Sequential Selective Flotation Process Flowsheet

A selective or sequential flotation flowsheet of two or more products. By utilizing selective flotation, two or more minerals in an ore are separated into individual high grade products. ORE TREATED: The most common of ores treated in this manner are lead zinc, copper-zinc-iron, copper-nickel, but application may be made to other two or three […]
