Flotation processes of various useful minerals are sequentially floatation, which is called preferential flotation process. The characteristics of the process can be adapted to the change of ore grade and has higher flexibility. It is more suitable for the primary sulfide ores with higher grade. For example, the flotation process of Xilin, Fankou and Lechang lead-zinc concentrators in China and the flotation process of Laisvall lead-zinc concentrator in Sweden are all of this kind.

Ore Property: After the mine sample test, Xinhai Mine Design Institute concluded that the ore was skarn copper, and main minerals were chalcopyrite and bornite, followed by magnetite and pyrite.

Xinhai Solution: Xinhai decided to adopt three stage open-circuit crushing, one stage grinding, differential flotation to get copper concentrate and sulfur concentrate, two stage dewatering process. Three stage open-circuit crushing adopted Xinhai jaw crusher, the crushing product was sent to cone crusher by belt conveyor for two or three stage crushing,then sent to Xinhai grid type ball mill for grinding and classifying.Then Xinhai added collector to the pulp for copper differential flotation and mixed slurry was sent to Xinhai JJF flotation cell to get qualified copper concentrate, followed by sulfur concentrate. The tailings were sent to Xinhai magnetic separator to separate qualified iron concentrate. Finally, copper and sulfur concentrate were transported to high efficient thickener, thickening underflow was filtered by plate press filter.

Principle: This process floats copper concentrate and other useful minerals together and gets mixed concentrate, then separates mixed concentrate to obtain qualified copper concentrate.

Ore Property: Shandong client commissioned Xinhai Mine Research Institute to conduct ore dressing experiment after collecting 50kg samples on the scene. After tested the ore properties of sample ore, Xinhai lab concluded that the main metal minerals of this project were copper, lead, zinc, and a certain amount of magnetite.

Xinhai Solution: Xinhai Mine Research Institute carried on preliminary exploration of its processing conditions and found that the copper recovery rate was the highest in bulk flotation process. Therefore, after discussed with client, Xinhai adopted two stage closed-circuit crushing, one stage closed-circuit grinding, middlings regrinding, copper lead bulk flotation - zinc flotation - copper lead separation process. Copper lead bulk flotation adopted one roughing, three scavenging, four cleaning process. Roughing and scavenging adopted Xinhai XCF flotation cell, cleaning used Xinhai BF flotation cell. Zinc flotation adopted one roughing, three scavenging, four cleaning process. Roughing and scavenging adopted KYF flotation cell, and cleaning selected SF flotation cell BF flotation cell was used in copper lead separation process. The dewatering of copper, lead and zinc concentrates used Xinhai efficient deep cone thickener+ceramic filter. The concentrate moisture was about 12% after dewatering.

Xinhai Solution: In recent years, the ore grade of this project has fallen down, and flotation index was not good. Therefore, Xinhai upgraded its flotation technology: adopt Xinhai JJF flotation cell to replace original flotation column, then add collector and frother as PH regulator, which strengthened concentration process and increased floating ratio of coarse grain. Finally, the recovery rate of copper concentrate reached above 94%, and copper concentrate grade was improved by 3%.

Xinhai Solution: Xinhai decided to adopt three stage opening crushing process, closed-circuit rod mill, ball mill and hydrocyclone, single copper flotation, concentrate scavenging and tailings reelection process. After crushing and screening, grinding, and classifying, qualified mineral particles were sent to Xinhai KYF flotation cell, BF flotation cell,the alkaline medium was adjusted to PH10 ~ 10.5. Then added copper inhibitors, which greatly improved foam properties. After one roughing, scavenging and cleaning, high-quality copper concentrate was obtained.
