Product Description
Nickel ore has good chemical stability, ductility, melt resistance and high temperature resistance and other excellent characteristics, is a very important non-ferrous metal raw materials, widely used in the manufacture of stainless steel, high nickel alloy steel and alloy structural steel. When the nickel content of nickel ore more than 3%, can be directly smelted, and used to produce a variety of nickel-containing materials; when the nickel content of nickel ore is less than 3%, it must be enriched through the beneficiation process to purify nickel, and then can enter the smelting process. Because the composition of different nickel ores is different, so in the beneficiation process, according to the composition of different nickel ores, choose the appropriate technology and equipment.
Extraction Process of Nickel Ore
Nickel ore mainly includes copper nickel sulfide ore and nickel oxide ore (laterite nickel ore). The extraction and processing methods of these two are very different: different extraction methods are selected according to the grade of nickel sulfide ores, and then nickel is prepared in different ways; the smelting methods of nickel oxide ores are usually divided into two types: dry and wet.

In copper-nickel sulfide ores, copper exists mainly as chalcopyrite, while nickel exists mainly as free nickel sulfides (e.g., pyrite, hematite, and pyroxene). A considerable portion of the nickel is present in a similar manner in pyromorphite, along with small amounts of nickel silicates. The most important extraction method is flotation, with magnetic separation and re-election usually being secondary extraction methods. In the flotation of copper and nickel sulphide ores, trapping and frothing agents are usually used in the flotation process of copper sulphide minerals. During smelting, nickel in the copper concentrate is lost, while copper in the nickel concentrate can be more completely recovered.
Oxidized nickel ores primarily use processes such as crushing and screening to advance the removal of large chunks of bedrock with a weak degree of weathering and low nickel content. This is because the nickel in oxidized nickel ores is usually dispersed in a similar manner in the surrounding rock minerals and is very fine grained. Therefore, it cannot be enriched by mechanical extraction methods and can only be directly smelted.

Common flotation methods for copper-nickel ores | Application Scenarios |
Copper-Nickel Mixed Flotation | Copper content is lower than nickel content. |
Copper-nickel separation | Coarser-grained, less tightly embedded copper-nickel ores. |
Preferential flotation of copper ore | The copper content of the ore is much higher than the nickel content. |
Copper-Nickel Mixed Flotation + Tailings Recovery | There are a variety of nickel minerals contained in copper-nickel ores. |

Working Flow
Nickel Ore Beneficiation Plant
When treating copper nickel sulfide ores, it is common to use traps and frothing agents to get better results because it is easier to recover copper from nickel concentrates. The treatment of nickel ores usually involves three processes: crushing, grinding and extraction. Magnetic separation and re-election are usually secondary extraction methods.
Crushing and screening: The mined copper-nickel sulfide ore is fed through a feeder into a jaw crusher for initial crushing. After the initial crushing, the coarse copper-nickel sulfide ore particles are then sent to the cone crusher through the conveyor belt for secondary crushing. After secondary crushing, the copper-nickel sulfide ore is screened by the screening equipment, and the qualified ore particles can be directly sent to the next grinding process. Unqualified ore should be returned to the cone crusher for re-crushing.

Unqualified ore should be returned to the cone crusher for re-crushing.
Grinding and screening: Qualified copper-nickel sulfide ore particles are sent to ball mill for grinding, and the ore particles are ground into ore powder. Then it will be sent to the spiral classifier for sorting, if the particle size meets the requirements, the next step of flotation and purification can be carried out. Particles that do not meet the requirements need to be returned to the ball mill for secondary grinding.
Flotation Separation: Classified qualified copper-nickel sulfide ore is sent to the mixing tank for full mixing, and then sent to the flotation machine with reasonable flotation chemicals. The specific flotation method needs to find professional extraction manufacturers to carry out extraction test analysis of mineral properties. After professional analysis, the flotation purification process flow will be customized to meet the requirements according to the actual situation.
Dewatering and drying: After flotation, the water content of the material is relatively high, and the flotation concentrate material is sent to the thickener for initial concentration and precipitation. In order to accelerate the drying rate of the product, it is usually dewatered and separated using a thickener and then dried using a drier to obtain the finished product.

Main Equipment
Nickel ore processing equipment is divided into two series of smelting processing equipment and mineral processing equipment, mainly including, crusher, vibrating screen, washing machine, dryer, rotary kiln, electric furnace, dust removal equipment, ball mill, flotation machine, magnetic separator, jigger etc.
The specific configuration of mineral processing equipment should be designed according to the nature of the ore and the corresponding optimal process. Different physical and chemical properties of different ores are different, need to use different beneficiation technology and equipment in order to achieve the best beneficiation effect.
