Crushing Process
Ore processing plant commonly has two processes: crushing & screening, beneficiation process.
In this process, large ore materials become small by the help of mechanical force. The crushing process is important during the treatment of ores. It is divided into four stages: crushing, grinding & classification, superfine crushing and micronization. It is a high energy-consuming operation, and its basic principle is “more crushing, less grinding”.
grinding and classification system
Ball mill: after crushing, ball mill is the key plant equipment which is used for further crushing. It is one of the widely used fine grinding plants in industrial production.
Classifier:
1.Combining the classifier with ball mill, the closed circulatory process is formed to classify ore sand.
2.Also, the classifier is used in gravity mill to classify ore sands and fine clay.
3.The classifier functions in ore pulp grading in metal ore dressing process.
4.The classifier works in the processes of desbmw and dehydration in ore washing operation.
Ball mill and classifier form a close circuit system,make the solotion meet requirement.
flotation processing part
When the solution gets into the mixing tank, mixing and join the chemical agents. According to sample analysis and experimental results, to join the collector (xanthate, R - OCSSNa), foaming agent (oil), activator (copper), inhibitors (lime).
Then solution enter into flotation machine, flotation is divided into roughing, scavenging, cleaning three stages.
First,solution go to roughing stage, upper air bubbles go into the cleaning, bottom flow go into scavenging, after the cleaning get concentrate and bottom flow , the bottom flow back into the roughing, concentrates go into the thickener.
After roughing, underflow get into the scavenging I, and after scavenging I ,bubbles back into the roughing, underflow into the scavenging II, scavenging II underflow get into tailings thickener, bubbles go into the scavenging I. After flotation system, tailings into thickener processing to improve the tailings solution density, recovery the water.Concentrate gets into thickener to process, then go into the filter press, through the filter press filter, get the ore fine.
