Ore Type: Cu-Pb-Zn
Adopting mixed flotation-concentrate regrinding process can reduce the grinding cost, and be easy to manage. Application of new non-toxic flotation reagents is efficient and environmental protection.
Mixed flotation-concentrate regrinding process is applied for Cu-Pb-Zn sulfide ore.
reative process, low operation cost
Cu-Pb mixed concentrate regrinding process saves the grinding cost without fine grinding all the ores are, and it makes further monomer dissociation to create favorable conditions for the separation of copper and lead.
Alead-zinc dressing plant in Yunnan, , due to the mining depth increasing, ore properties had changed and the grade of lead and zinc concentrate decreased, so the original flotation is not suitable. After field investigation and analysis, Xinhai determined the process according to multi tests: mixed flotation, preferential flotation of copper lead concentrate, regrinding and re-floating of copper lead concentrate, and equipped with the Xinhai equipment. Indexes comparison as follow:
|Comparison of Reformation||Process||Capacity
|Copper Recovery Rate
|Pb Concentrate Grade/%||Zinc Concentrate Grade/%||Service Life of Equipment Liners/Day|
|Before Reformation||Preferential Flotation||500||78.53||35.68||83.49||50|
|After Reformation||Mixed Flotation||680||83.45||50.13||84.68||90|
After the technical reformation, this plant increased the output value of nearly 30000 yuan/day, and the profit increasing of 26000 yuan/day. The economic benefit is remarkable.
