Graphite Ore Processing Optimal Processes And Equipment

Types of graphite ore

Different graphite ores are suitable for different processing flowsheets. Natural graphite, according to crystal diameter, is usually divided into:

• Amorphous graphite (crystal diameter less than 1 μm).
• Crystalline graphite (crystal diameter greater than 1 μm). Crystalline graphite, often referred to as generally refers to flake graphite, which can be divided into large flake graphite (crystal diameter greater than 147 μm) and small flake graphite (crystal diameter less than 147 μm).

Amorphous graphite ore processing flowsheet

Amorphous graphite ore has a high grade (generally containing 60% to 80% carbon), but the particles of graphite ore are extremely small and often embedded in clay, making flotation separation impossible. Therefore, many graphite mines directly pulverize and grind the mined raw ore to sell graphite powder products.

The traditional process is raw graphite ore - crushing - drying - grinding - grading -packaging.

Flake graphite ore processing flowsheet

Flake graphite has good flotation, so froth flotation is an effective beneficiation method. Large flake graphite has excellent properties and wide application. In the beneficiation process, we should protect the surface of large flake graphite from damage and separate it in time. Therefore, we use the method of a multi-stage grinding and multi-stage flotation to process flake graphite.

Graphite ore crushing

(1) Raw ore feeding particle size: 300~500mm;

(2) Final product particle size: 10~20mm;

(3) The commonly used crushing process is a two-stage open circuit or a three-stage open circuit;

(4) The equipment is a jaw crusher for primary crushing, a cone crusher, or a hammer crusher for final crushing.

Graphite ore flotation separation

(1) Collector: kerosene and diesel are more popular options;

(2) Foaming agent: the most popular option is 2# oil;

(3) Regulator: If the graphite contains pyrite, lime is often added to suppress it. When gangue contains quartz, mica, or silicate minerals, sodium carboxymethyl cellulose, water glass, or a mixture of these two agents in proportion are often used to inhibit gangue;

(4) Equipment: Mostly use a special flotation machine or a special flotation column for graphite ore.
