Whether scale design of ore-dressing plant is appropriate can be directly related to future production and economic benefits, so properly determining the size of ore-dressing plant is very essential.

According to the needs of state, local and enterprise construction, feasibility research should be conducted. The following factors should be considered.

1. Requirement of product quantity

We should combine requirements from government and customers with geological resources, deposit condition, building conditions(site, transportation, water supply, power supply, etc) as well as possibility of ore-dressing process and economic rationality.

2. One time construction and phased construction

Medium and small sized ore-dressing plant can be completed at once, while large-sized ore-dressing plant can be built progressively, so that productive force can be formed in a short time.

3. Dispersion and centralization of factory

The scale of ore-dressing plant should correspond to ore supply ability of quarry. Plants are often built dispersedly on quarry with abundant resources and distant resource spots and vice versa.

4. The service life of ore-dressing plant

It is determined by industrial reserves of ore deposit and the scale of ore-dressing plant.

The differentiation of ore-dressing plant:

Generally, the scale of industrial enterprise is determined by quantity of finished products. For ore-dressing plant, the amount of concentrate differs based on different ore grades.

To have rules to follow in ore-dressing plant design when determining the production and living facilities standard, level of technical equipment and investment in infrastructure, we divide ore-dressing plants into large, medium and small sized types according to resources and ore.
