Analysis of Construction Costs for Graphite Processing Plants

Heilongjiang-3000TPD-Graphite-Processing-Plant

Graphite, as a strategic mineral raw material, exhibits significant variability in construction investment for its processing plants, which is notably influenced by resource endowment, production scale, and process flow. This paper systematically analyzes the cost composition and core driving factors, aiming to provide a theoretical reference for mining enterprises' investment decisions, thereby facilitating optimal resource allocation and enhancing project economic efficiency.

1. Flotation Method

(1) Core Process

• Separates graphite from gangue minerals through multi-stage grinding and multi-stage selection.

2. Gravity Separation Method

(1) Auxiliary Means

• Often used as a roughing step to pre-discard a portion of low-density tailings.

3. Magnetic Separation Method

(1) Auxiliary Means

• Primarily used to remove iron-bearing impurities, often serving as pretreatment before flotation or as a purification step for concentrates.
