Introduction to Copper Selection Equipment

Copper ore refers to the collective term for naturally occurring mineral aggregates containing copper. Copper ores are generally composed of copper sulfides or oxides mixed with other minerals, which react with sulfuric acid to produce blue-green copper sulfate. China primarily mines chalcopyrite (a compound of copper, sulfur, and iron), followed by chalcocite and bornite. Copper ores are typically found at greater depths underground and have larger particle sizes. Therefore, the process design of copper equipment must be rational to ensure the grade of the concentrate.

Select Copper Equipment Type and Prospects

Currently, the commonly used copper ore fine crushing equipment in China includes hammer crushers, jaw crushers, roller crushers, cone crushers, and impact crushers that have emerged in recent years. These can be categorized into hammer, extrusion, and impact types based on their functions. During the rapid development period of copper ore beneficiation equipment, efforts have been made to research and produce various copper selection machines, with heavy machinery learning and catching up over the past many years, continuously improving and perfecting copper ore beneficiation equipment, and gradually stepping up the pace, now reaching a certain level of technology. At the critical period of national industrial and industrial development, the development of copper ore beneficiation equipment should maintain its leading position, assisting in the use of ore, paving the way for the development of the metal industry.

Selection Process for Copper Equipment Technology

The copper ore from mining is initially crushed by a jaw crusher, then, after being broken to a reasonable fineness, it is evenly fed into a ball mill by a hoist and a feeder, where the ore is further crushed and milled.

2. Copper ore fines processed through ball mill grinding are then moved to the next stage: classification. The spiral classifier uses the principle that solid particles settle at different rates in a liquid due to their varying specific gravities to wash and classify the ore mixture.

3. After being cleaned and graded, the mineral blend is fed into a magnetic separator. Due to the varying magnetic saturation coefficients of different minerals, the magnetic and mechanical forces separate the magnetic materials from the blend. The mineral particles, initially separated by the magnetic separator, are then sent to a flotation machine, where different reagents are added based on the mineral characteristics to separate the desired minerals from other substances.

After the minerals required for beneficiation are separated, due to their high moisture content, they must be initially concentrated in a concentrator and then dried in a dryer to obtain dry minerals. Copper concentrate grade reaches 45%!

There are mainly two methods of copper smelting for copper equipment selection: fire smelting and hydrometallurgy (SX-EX).

1. Fire refining: Produces cathode copper, also known as electrolytic copper, through melting smelting and electrolytic purification, generally suitable for high-grade sulfide copper ore.

In addition to copper concentrate, scrap copper is one of the primary raw materials for refining copper, encompassing both old and new scrap copper. Old scrap copper originates from old equipment and machinery, abandoned buildings, and underground pipelines; new scrap copper comes from discarded copper shavings from processing factories (with a yield ratio of around 50%). Generally, the supply of scrap copper is stable, and it can be categorized as follows: Bare copper: grade above 90%; Yellow copper (wires): copper-containing materials (old motors, circuit boards); Copper produced from scrap copper and similar materials is also known as recycled copper.

2. Wet Process: A shipment suitable for low-grade copper oxide, with the refined copper produced being called Electrolytic Copper.

3. Characteristics of the fire and wet processing methods

Comparing the fire and wet methods of copper production, the following characteristics can be observed:

The latter's smelting equipment is simpler, but with higher impurity content, serving as a beneficial supplement to the former.

(2) The latter has limitations, subject to the grade and type of ore.
