Nickel ore is extracted and enriched to obtain nickel metal, which is widely used in modern industry. Ore dressing recovery rate and concentrate grade are the key to ensuring the economic benefits of mining companies, and the selection and configuration of ore dressing equipment are the top priority to ensure the concentrate grade and ore dressing recovery rate. This article will introduce the classification of nickel ore dressing equipment and how to configure equipment for nickel ore dressing plants of different sizes.
Suitable for nickel ore dressing plants with small processing capacity (processing capacity is generally 100-300 tons/day). The configuration points include:
Crushing equipment: Select a jaw crusher with a processing capacity of 10-20 tons/hour.
Grinding equipment: Select a small ball mill, and the grinding fineness is controlled at -0.074mm, accounting for 60%.
Classification equipment: Select a spiral classifier to ensure that the grinding product reaches the required fineness.
Floatation equipment: Select a mechanical stirring flotation machine with a processing capacity of 5-10 tons/hour.
Dehydration equipment: Select a filter with a processing capacity of 5-10 tons/hour.
Suitable for ore dressing plants with medium processing capacity (processing capacity is generally 300-1000 tons/day), the configuration plan includes:
Crushing equipment: select a jaw crusher and a cone crusher with a processing capacity of 50-100 tons/hour.
Grinding equipment: select two ball mills, and the grinding fineness is controlled at -0.074mm, accounting for 70%.
Classification equipment: select two hydrocyclones to ensure that the grinding products reach the required fineness.
Floatation equipment: select two aerated mechanical agitation flotation machines with a processing capacity of 20-50 tons/hour.
Dehydration equipment: select two filter presses with a processing capacity of 20-50 tons/hour.
Suitable for ore dressing plants with large processing capacity (processing capacity is generally 1000~3000 tons/day), the configuration plan includes:
Crushing equipment: Select two jaw crushers and two cone crushers with a processing capacity of 200-500 tons/hour.
Grinding equipment: Select four ball mills, and the grinding fineness is controlled at -0.074mm, accounting for 80%.
Classification equipment: Select four hydrocyclones to ensure that the grinding products reach the required fineness.
Floatation equipment: Select four aerated flotation machines with a processing capacity of 100-200 tons/hour.
Dehydration equipment: Select four vacuum filters with a processing capacity of 100-200 tons/hour.
In addition, when we choose nickel ore dressing equipment, in addition to paying attention to the size of the production scale of the ore dressing plant, we must also pay attention to the ore dressing process, the energy consumption of the plant and environmental protection issues. When choosing nickel ore dressing equipment, you should choose nickel ore dressing equipment that is energy-saving, efficient, of high quality and has a high additive ratio.
