The ore is a sulfide copper ore containing heads of approximately: copper 0.45, iron 3.5, molybdenum 0.006, and zinc 0.06 per ore sample. Prior flotation of this ore has employed, in the flotation cell, the addition of pine oil as required to optimize froth, ordinarily resulting in a total pine oil concentration of about 0.24 lb./ton.

Mining Industry Copper Sulfide Ore and Flotation Process

2019-7-9  1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

Copper Mining and Extraction Sulfide Ores

Metals are often found as compounds in ores. An ore is a rock or mineral that has enough metal in it to make it worth extracting. Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon.

Copper Nickel Flotation 911 Metallurgist

2017-6-15  The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates. One of the ores studied was taken from a test pit; the other was taken from a test shaft. The samples were quite similar except that the pit sample analyzed 0.35 pct Cu and 0.11 pct Ni and the shaft sample analyzed 0.69

Flotation of sulfide minerals Inspiration Consolidated

What is claimed is: 1. In the process of froth flotation concentration of a sulfide mineral which minimizes the collection of slimes and in which an aqueous pulp of an ore containing such mineral is subjected to a flotation operation to produce a final high recovery of such mineral in a flotation concentrate, the improvement comprising carrying out said flotation with a polyglycerol added

The interaction of OM with sulphide minerals and its effects on their flotation are little understood. Although chalcopyrite recovery and grade are generally high in the flotation of most copper and molybdenum ores, this is not the case for molybdenite, whose flotation is much lower and sensitive to changes in hydrodynamic and pulp conditions in the flotation cell [9,10,11,12].

Froth flotation is a process in which hydrophobic particles attach to bubbles forming particle–bubble aggregates, which are transported to the top section of the cell where they overflow to form the concentrate. Particles also reach the concentrate by entrainment, which is a non-selective process that leads to low concentrate grades. The objective of this work was to study and compare the

The presence of clay in the ore is the main reason for unstable froths and lowered frothing power. It has been shown that destabilization of frother takes place in the presence of ultrafine particles (Srdjan 2007). It is a common practice that during flotation of porphyry copper ores containing clay minerals, the copper
