Mineral Analysis & Quality Control in Moroccan Mining Operations

Mineral Analysis & Quality Control: Scientific Excellence in Moroccan Mining

Modern mining operations in Morocco employ advanced analytical techniques to ensure mineral quality, purity, and consistency. The3Rocks utilizes state-of-the-art testing methods including X-Ray Fluorescence (XRF), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and spectroscopic analysis to verify every shipment.

Laboratory Testing Methods

X-Ray Fluorescence (XRF) Analysis

Primary Use: Rapid elemental composition analysis

• How It Works: X-rays excite atoms in the mineral sample, causing them to emit characteristic fluorescent radiation
• Advantages: Non-destructive, fast results (2-5 minutes), minimal sample preparation
• Applications: Lead (86% purity), copper (8-21%), zinc (+37%), iron (≥56%)
• Accuracy: ±0.5% for major elements
• Sample Size: 1-10 grams

Moroccan Standards: Our facilities use Bruker and Thermo Fisher XRF equipment calibrated to ASTM E1621 standards.

Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

Primary Use: Trace element and high-precision analysis

-Precision: Parts per billion (ppb) detection

• Process:
  1. Sample dissolution in acid
  2. Nebulization into argon plasma (7,000-10,000°C)
  3. Mass spectrometer detection
• Applications: Cobalt (42%+), antimony (30%+), trace contaminants
• Analysis Time: 15-30 minutes per sample

Quality Assurance: ISO/IEC 17025 accredited laboratories in Morocco

Atomic Absorption Spectroscopy (AAS)

Primary Use: Metal concentration measurement

• Technique: Measures light absorption by atomized sample
• Sensitivity: Parts per million (ppm) to parts per billion (ppb)
• Best For: Copper, zinc, lead, iron content verification
• Sample Preparation: Acid digestion required

Physical Property Testing

Density Measurement (Barite Specification)

• Target: 4.18-4.28 specific gravity for barite
• Method: Pycnometry or Archimedes principle
• Importance: Critical for drilling fluid applications
• Standard: API Specification 13A

Particle Size Distribution

• Methods:
  • Sieve Analysis: For larger particles (ore)
  • Laser Diffraction: For powders and concentrates
  • Sedimentation: For very fine materials
• Application: Lead powder (76% purity), barite powder

Moisture Content Analysis

• Standard: ASTM D2216
• Target: \u003c2% for concentrates, variable for ore
• Impact: Affects shipping weight and processing

Mineralogical Analysis

X-Ray Diffraction (XRD)

Purpose: Crystal structure and mineral phase identification

• Technology: Analyzes diffraction patterns from crystal lattices
• Information Provided:
  • Mineral composition (galena, chalcopyrite, sphalerite, etc.)
  • Crystal structure
  • Quantitative phase analysis
• Sample Requirements: Powdered sample, 1-5 grams

Scanning Electron Microscopy (SEM-EDS)

Purpose: Microstructural analysis and elemental mapping

• Magnification: Up to 100,000x
• Capabilities:
  • Surface morphology
  • Particle size and shape
  • Energy Dispersive Spectroscopy (EDS) for elemental composition
  • Contamination identification
