The milled ore/gangue powder is mixed with a liquid and aerated in the flotation step. The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and in the case of copper/ molybdenum ores separates molybdenite from copper sulphide.
The process of the plant was once roughing, twice scavenging, four times cleaning, and molybdenum ore grade was 0.38%. In recent years, due to the mining depth increasing, ore properties had changed, so the flotation index became poor leading to more molybdenum metal loss.

from the ore by crushing, grinding, and flotation. One ton of ore yields four to six pounds of molybdenum. Henderson is the worlds largest primary molybdenum mine. Since 1976, Henderson has produced more than 160 million tons of ore and 770 million pounds of molybdenum. The Climax mine produced ore from 1918 until 1995.

The main useful mineral in single molybdenum ore is molybdenite. Because of the good natural buoyancy of molybdenum ore, Xinhai often adopts direct floatation process after crushing and grinding. And the main useful minerals in the copper molybdenum ore are chalcopyrite, pyrocopper, molybdenum and so on.
Molybdenum Dressing Production Line Yantai Jinpeng Mining . Combined but flotation priority process is the most use in molybdenum ore with copper , the valuable minerals in the molybdenum ore with gold are molybdenite. How is Molybdenum Extracted Stanford Advanced Materials. May 23, 2017 . Molybdenum ore beneficiation method.
This Molybdenum Flotation metallurgical program consisted of performing one rougher and four batch cleaner flotation tests on the sample of sulphide ore. The nominal primary grind P80 selected for this series of tests was 150181;m. The cleaner tests were designed to investigate the effect of a regrind stage between rougher and cleaner flotation.

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

The ore is mined from an open pit, crushed, and fed to ten ball mills. The concentrator is divided into two parallel comminution flotation sections, so that five ball mills feed each flotation section. Both sections consist of three bulk copper and molybdenum rougher flotation lines, and the rougher concentrate is transferred to a regrinding stage.

Flotation; Once the ore has been crushed and ground, the metallic minerals are then separated from gangue minerals (or the molybdenum and copper from each other) by flotation processes, using a wide variety of reagents.

Molybdenum mining in the United States produced 65,500 metric tons of molybdenum in 2014, worth US$1.8 billion. The US was the worlds second largest molybdenum producer, after China, and provided 25% of the worlds supply of molybdenum.. The US was a major exporter of molybdenum; net exports made up 48% of US production.
Molybdenum is contained in various minerals, but only molybdenite (MoS 2) is suitable for the industrial production of marketable molybdenum products. Molybdenite can occur as the sole mineralization in an ore body, but is often associated with the sulphide minerals of other metals, notably copper.
This molybdenum flotation circuit, based on 250 500 tons per 24 hours is designed for low grade molybdenum ore having high grade streaks and with pyrite quartz gangue. It is also basically sound for many other friable sulphide ores, such as antimony, silver and even some lead ores.
Water quality, flotation equipment size and type, temperature, and ore body variation are just a few of the variables affecting the flotation process. Copper/Molybdenum Ore. The figure above is a simplified flow sheet showing the basic steps involved in a copper mill producing the byproduct molybdenum.
