What Equipment Processes Metallic-Bearing Ores Identified in Geological Samples?

10 November 2025
The equipment used to process metallic-bearing ores identified in geological samples depends on the specific ore type, its composition, and the desired end product. The typical processes and equipment include:
1. שבירה וטחינה
- מַפצְצֵי לסת: Reduces large ore rocks to smaller chunks.
- מַכְסָת מְחוּזָקִים: Provides secondary crushing.
- מכונות כדוריותאומְטַחֲנוֹת רוֹד: Grind the crushed ore to finer particles for further processing.
2. Ore Separation
- ציוד מיון: Separates ore particles based on size.
- הידרוcyclones: Classify particles by size and density.
- Magnetic Separators (for magnetic ores like magnetite): Extract magnetic materials from ore.
- Gravity Separation Equipment (for heavy metallic ores like gold):
- Shaking Tables
- Spiral Concentrators
- Jigs
3. ציפה
- Flotation Cells or Tanks: Separate metallic components from gangue by using chemical reagents, surfactants, and air bubbles.
4. Heap Leaching or Agitation Leaching
- Leaching Tanks or Heap Pads: Extract metals like gold, copper, or uranium using a leaching agent like cyanide or sulfuric acid.
5. Smelting and Refining
- Blast Furnaces: Smelt iron ores into pig iron.
- Electric Arc Furnaces: Used for melting and refining metals.
- Refining Equipment: Electrolytic cells are used for extracting pure metal after smelting (e.g., electrolytic refining for copper).
6. Drying and Roasting
- Rotary Kilns: Used to remove moisture or change the chemical composition of ores via heat.
- Dryer Systems: Removes excess moisture from crushed, ground, or separated materials.
7. Analytical Equipment
Though not for processing, analyzing and testing ores before processing is critical:
- X-Ray Fluorescence (XRF) Spectrometers
- Scanning Electron Microscopes (SEM)
- Atomic Absorption Spectrometers
The exact configuration and combination of equipment depend on the type of ore, the processing method (gravity, flotation, magnetic separation, leaching, etc.), and the metallurgical properties of the minerals being extracted.
