However, behind high-performance copper products lies a rigorous beneficiation process, in which crushing and grinding account for the highest energy consumption and determine the final recovery rate of copper concentrate.

This article provides a professional and SEO-friendly overview of copper ore crushing technology, including ore characteristics, process design, equipment selection and key optimization strategies for efficient plant operation.


1. Understanding Copper Ore: The Foundation of Crushing Design

Different types of copper ore show huge variations in hardness, abrasiveness and liberation size. Understanding ore properties is the starting point for selecting suitable crushing equipment.

Common copper ore types:

  • Porphyry copper ore – medium hardness, stable structure, high processing capacity required.

  • Sandstone copper ore – brittle, easier to crush, suitable for simplified circuits.

  • Sulfide copper ore (chalcopyrite, bornite, chalcocite) – high hardness and abrasiveness, requiring wear-resistant liners.

  • Oxide copper ore – softer, less abrasive, but requires precise particle size control to improve leaching or flotation efficiency.

Liberation size (0.074–0.2 mm) is a key parameter determining how fine the ore needs to be crushed before grinding.


2. Typical Crushing Process for Copper Ore

To achieve an optimal feed size for the grinding mill (usually ≤10–12 mm), a multi-stage crushing system is typically used.

(1) Three-stage closed-circuit crushing (used in medium & large copper mines)

Jaw Crusher → Cone Crusher (Secondary) → Cone Crusher (Fine) + Vibrating Screen

Advantages:
✔ Stable particle size
✔ Low over-crushing ratio
✔ High production capacity
✔ Lower energy cost for grinding

This is the mainstream solution for porphyry copper deposits in countries like Chile, Peru and Indonesia.

(2) Two-stage crushing (for soft ore or small-scale mines)

Jaw Crusher → Cone Crusher + Screen

Advantages:
✔ Reduced investment
✔ Simple layout
✔ Fast construction period


3. Equipment Selection: Key Factors for Copper Ore Crushing

kaolin powder processing Systems


There are four types of kaolin powder processing: coarse powder processing (0-3MM), fine powder processing (20 mesh-400 mesh), ultra-fine powder deep processing (400 mesh-1250 mesh) and micro powder processing (1250 mesh-3250 mesh)

231109.jpg

The kaolin powder making process is divided into four stages: crushing, grinding, grading, and powder collection;

Stage One: Broken

The bulk kaolin materials are crushed by the crusher to the feeding fineness (15mm-50mm) that can enter the grinding mill.

Second stage: grinding

The crushed kaolin small pieces are sent to the silo through the elevator, and then sent to the grinding chamber of the mill uniformly and quantitatively through the vibrating feeder for grinding.

For fine powder processing, LM vertical roller mill, MTW European version mill, and 5X European version smart mill can be used;

For ultra-fine powder processing, MW ring roller micro-powder mill and LUM ultra-fine vertical mill can be used; for coarse powder processing, CM European-style coarse powder mill can be used.

The third stage: grading

The ground materials are classified by the powder selector, and the unqualified powder is classified by the powder selector and returned to the main machine for re-grinding.

The fourth stage: gathering fans

Powder that meets the fineness will enter the dust collector with the air flow through the pipe for separation and collection. The collected finished powder will be sent to the finished product silo through the conveyor through the discharge port, and then packaged in a powder tanker or automatic baler.
