under the conditions of maximum flotation. Key words: wolframite; adsorption; hydroxamate; flotation 1 Introduction Wolframite is the most important tungsten-bearing mineral, which has been mined and processed for a century in China. Because of its crispness property, wolframite slime produced in the comminution process
plant ore is listed in Table 1. Batch flotation tests were carried out in XFG-C model aeration hanging cell flotation machine. A 0.75 L flotation cell was used for all batch flotation tests. For rougher flotation, approximately 400 mL mill discharge (solid content at around 60%) was added to the cell with a stirring speed set at 1650 rpm, then
The wolframite ore has a high depletion rate, low grade, coarse grain size, high density, low hardness, easy mud formation and deep color, which is mainly extracted by the gravity separation process. China's wolframite ore beneficiation production has a history of more than 70 years and has accumulated rich experience, which can be summarized ...

Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing, to liberate and concentrate those valuable minerals. 1.3 Run-Of-Mine Material and Minerals. Generally, mineral processing begins when an ore is delivered from a mine, to a processing facility.
Vieceli et al. [92] used response surface methodology to optimize the flotation process of lepidolite ore, investigating the effects of pulp pH, flotation collector dosage, and flotation time on lithium recovery and lithium grade. These models were developed based on experimental data obtained from a complete 2–3 factorial design and a ...
The shear-flocculation flotation process and oil agglomeration flotation process have also been proposed for fine wolframite flotation. ... The concentrate grade increased by 2.4% from the fifth to the eighth flotation cell and increased by 22.3% from the fifth to the eighth ... Separation of wolframite ore by froth flotation using a novel ...
Now more than 100 different minerals are commercially recovered by flotation and some mills process as much as 50,000 tons of ore every 24 hours. ... Different Types of Flotation Cells.

Medialan has preferable flotation performance to wolframite, under the conditions of the best flotation pH value 7.0 and low dosage, wolframite recovery is up to 80 %. Medialan shows poor flotation performance to quartz, but better to fluorite and calcite. However, fluorite and calcite are inhibited in a certain degree by adding medialan mixed with sodium silicate. …
