Introduction. Flotation is the common copper processing technology, which can be used for sulfide ore and oxide ore. The copper flotation plant usually includes following steps: crushing and screening, stage grinding and flotation, thickening and dewatering, and copper concentrates recovery.
Flotation is a commonly used process in the beneficiation of copper ore. It can be used to separate copper sulfide ore or copper oxide ore. The main flow of copper ore flotation is roughly as follows: ore crushing and screening → stage grinding stage Flotation → concentration and dehydration → copper concentrate.

It is well known that different milling procedures may result in different flotation responses. In the present study, the effect of various grinding conditions such as wet or dry grinding and addition of lime to the mill compared to the flotation cell on the flotation of two different copper sulphide ores was investigated.
Flotation is main beneficiation method of copper ore. It can be also treated with magnetic separation, gravity separation and wet smelting, etc. According to the beneficiation process, the copper ore processing flow can be: crushing – grinding – classifying – flotation – copper concentrate and tailings process. 1.
【Raw ore】 copper oxide 【Content】 2%-5% 【The recovery rate of flotation experiment can reach】85%. Combining the above experimental results and the customer's strength of our factory, the customer decided to choose us to do the copper ore dressing test for him. The experiment process is as follows: feeding-crushing-grinding-flotation.
Copper Ore Crushing, Grinding & Flotation. Crushing and Grinding You will note that the Oracle Ridge project has utilized a two-stage crushing circuit with a double acting jaw crusher and cone crusher. In order to utilize this system, the jaw crusher is oversized to produce all -5 material for the cone mill with a screen in closed circuit.
Flotation is the common copper processing technology, which can be used for sulfide ore and oxide ore. The copper flotation plant usually includes following steps: crushing and screening, stage grinding and flotation, thickening and dewatering, and copper concentrates recovery.
