《英语单词collective flotation的用法讲解》

Collective flotation，又称集体浮选，是普遍采用的一种矿石精选方法，它是一种利用液体或悬浮液中的涡流和浮力，使矿石区分重轻来选出质量较高的矿石的方法。集体浮选，其特点是把被选矿石从水溶液中较省力地进行分离。

Collective flotation is a process of separation of minerals by their hydrophobicity in which a mixture of mineral grains is dispersed into a fluid medium, usually water, which is saturated with air or nitrogen. The mixture is agitated by mechanical means and the mineral grains rise to the surface of the liquid, attaching themselves to air bubbles and forming a froth.

Collective flotation has many applications in mineral processing, such as the separation of copper and nickel from their ores, the separation of low grade copper from high grade copper, the recovery of iron from iron ore, and the recovery of rare earth minerals from their ores. It is also used for the preparation of flotation products for process mineralogy and for the improved recovery of molybdenum, cobalt and other valuable minerals.

Collective flotation has been applied to a wide range of industrial processes including wastewater treatment, chemical and mining. As it is a relatively simple process, it is relatively easy to scale up and can be used in many different types of industries.

In conclusion, collective flotation is a process that has many applications both in the mineral processing and in the industrial arena. It is an effective means of separating material by their hydrophobicity and air bubbles, providing a relatively low energy process that can be scaled up or down depending on the requirements.
