QC

Ensuring Excellence in Every step of production and export

  • Production Overview and QC Procedure:

    • ZPFA HOLDING produces copper powder concentrate with a grade ranging between 72-80% purity.
    • The product is derived from electrowinning cells and undergoes a detailed quality control (QC) process before shipment.
  • Step 1: Draining Liquids (PLS):
    • Copper powder from electrowinning cells is poured into jumbo bags.
    • The bags are designed to allow the pregnant leach solution (PLS) to drain out.
    • The draining process occurs under gravity and takes several hours to ensure maximum removal of residual liquids.
  • Step 2: Weighing and Sampling:
    • After draining, the jumbo bags are weighed to determine the net weight of the copper powder.
    • Samples are collected from the bags for chemical analysis.
  • Step 3: Chemical Analysis:
    • Samples are sent to a trusted third-party laboratory for detailed chemical testing.
    • The lab verifies the copper content to ensure it meets the specified grade range of 72-80%.
  • Step 4: Shipment Preparation:
    • Once the lab results confirm the quality, the copper powder is prepared for shipment.
    • The jumbo bags are shipped to customers alongside all relevant lab results and documentation.
  • Customer Due Diligence:
    • Customers may conduct their own quality verification by sending samples to their trusted laboratories.
    • This step ensures the product meets their specific requirements and quality standards.
  • Quality Assurance:
    • ZPFA HOLDING QC process ensures consistent product integrity and reliability.

Quality Control at Celestine Mine in Zamin Pouyan Faraz Asia Company

At Celestine Mine, quality is our top priority. Our dedicated Quality Control (QC) team ensures that every step of our mining process meets the highest industry standards. From extraction to final product, we are committed to delivering excellence.

Quality control (QC) for enriched and graded celestite ore involves multiple stages to ensure the material meets specifications before being shipped to customers. Here’s an overview of the QC process using SGS or other trusted companies (Société Générale de Surveillance) services:

Our Quality Control Procedure

Before Loading into Containers (Initial Inspection)

  1. Sampling Process:
    • Random Sampling: SGS or other trusted companies take representative samples from stockpiles or conveyor belts.
    • Standard Sampling Methods: Compliance with international standards (e.g., ISO or ASTM) for accurate sample representation.
  2. Laboratory Analysis:
    • Purity Analysis: Determines the percentage of SrSO₄ (celestite) to ensure it meets the grade (e.g., 90% or above).
    • Impurity Testing: Analyzes for SiO₂, BaO, Fe₂O₃, and other impurities.
    • Moisture Content: Ensures the material is dry enough to prevent contamination during transport.
  3. Certification:
    • SGS or other trusted companies provide a Certificate of Analysis (CoA), confirming the composition and quality of the celestite.
    • The CoA is shared with both the seller and buyer.
  4. Container Inspection:
    • SGS or other trusted companies spects the containers for cleanliness, structural integrity, and suitability for transporting celestite ore.
  5. Weight Verification:
  6. Conducted using certified weighbridges to ensure accurate tonnage.

After Arrival at Destination (Continuous Monitoring)

  1. Unloading Supervision:
    • SGS or other trusted companies supervise the unloading process to ensure the material is handled correctly and matches the shipping documents.
  1. Resampling and Analysis:
    • Representative Sampling: SGS or other trusted companies re-sample the delivered ore to verify consistency with the pre-shipment CoA.
    • Lab Testing: Analysis includes purity, impurity levels, and physical properties such as particle size distribution.
  1. Weight Confirmation:
    • A final weight check ensures no discrepancies in the shipped quantity.
  1. Discrepancy Management:
    •  If differences are found between pre-shipment and post-delivery analyses, SGS mediates to resolve disputes between seller and buyer.
  2. Final Certification:
    • SGS or other trusted companies issue a Destination CoA, verifying the quality and quantity of the delivered material.
