KEY TAKEAWAYS
- Upgrading lower-grade ROM to high-quality 40/42 chrome concentrate can enhance profitability for independent miners.
- Beneficiation methods like gravity separation, DMS, and magnetic separation are key to transforming chrome ore.
- Oreways provides a consistent market for upgraded chrome concentrate, supporting smaller miners in reaching buyers.
- A focus on quality and efficiency during processing ensures better market access and competitive pricing.
Chrome mining is essential to the global stainless-steel
industry, with South Africa being one of the largest
producers of chrome ore. Independent miners,
particularly in South Africa, often face the challenge
of turning lower-grade materials like 30/32 and 32/34
ROM (Run of Mine) or sweepings into a high-quality 40/42
chrome concentrate. However, with the right processing
techniques and equipment, this transformation can be
highly profitable.
What makes the opportunity even more lucrative is that
Oreways Mining, a major chrome buyer in South Africa, is
always looking to develop and support independent miners
by providing a reliable market for their upgraded
product. This guide outlines how independent miners can
process lower-grade ROM to achieve a higher-grade
concentrate and ultimately sell to key players like
Oreways.
Step 1: Understanding the Economic Benefits of Processing Lower-Grade Chrome Ore
Lower-grade chrome ore such as 30/32 and 32/34 ROM may seem less appealing initially due to its lower chromium content (Cr₂O₃). However, it offers significant opportunities when upgraded. Purchasing this ore at a lower cost and then processing it into a high-quality 40/42 concentrate can significantly increase profitability.
- Increased Marketability: Upgrading low-grade ROM allows you to sell to larger chrome buyers in South Africa, including Oreways Mining, which actively seeks quality chrome concentrate for their operations.
- Cost Efficiency: Lower-grade ore is often less expensive to acquire, and the beneficiation process, while requiring investment, generates a product that commands higher prices.
- Long-Term Growth: By consistently producing high-grade concentrate, independent miners can build a reliable market with established buyers, creating opportunities for growth.
Step 2: Finding the Right Chrome Wash Plant
Choosing the right wash plant is crucial for
independent miners aiming to transform lower-grade
30/32 and 32/34 ROM into high-grade 40/42 chrome
concentrate. The right wash plant will offer all the
necessary services and equipment, from crushing and
grinding to gravity separation and dewatering.
Look for wash plants that provide:
- Comprehensive Equipment: Crushers, mills, spiral concentrators, and magnetic separators to ensure the ore is fully processed.
- Cost-Effective Solutions: Plants that use efficient beneficiation methods to minimize operational costs.
- Sustainability Measures: Water recycling systems and environmental safeguards to reduce waste and impact.
When assessing a chrome wash plant, it’s essential to
evaluate its equipment, efficiency, and ability to
meet your specific production goals. For a detailed
guide on how to assess a wash plant and ensure it
meets your needs, read our article

Operation.
By partnering with the right wash plant, independent
miners can streamline their beneficiation process,
improve the quality of their product, and increase
profitability.
Step 3: Processing Techniques for Upgrading Chrome Ore
Upgrading 30/32 and 32/34 ROM into high-quality 40/42 chrome concentrate involves several commonly used beneficiation techniques, each with its own advantages:
- Gravity Separation: This cost-effective method uses equipment like spiral concentrators and shaking tables to separate chrome particles from waste, based on their density differences.
- Dense Medium Separation (DMS): Ideal for processing a wide range of particle sizes, DMS uses a dense liquid medium to separate chrome from waste. It is highly efficient but requires more significant upfront investment.
- Magnetic Separation: This method is used to remove iron-based impurities, improving the overall quality of the chrome concentrate, making it more attractive to buyers.

Step 4: Potential Challenges and Solutions
Processing lower-grade chrome ore is not without its challenges. Here are a few obstacles and how to overcome them:
- Inconsistent Ore Quality: Regular testing and monitoring are essential to maintain consistent product quality. Implementing real-time ore analysis systems can help optimize the beneficiation process.
- Water Consumption: Gravity separation and DMS require significant amounts of water. Investing in water recycling systems can reduce costs and minimize environmental impact.
- Equipment Maintenance: Crushers, mills, and separators require regular upkeep to ensure efficient processing. Implementing a predictive maintenance program can minimize downtime.
Step 5: Market Insights and Selling to Chrome Buyers
Once you’ve successfully upgraded your 30/32 or 32/34 ROM into a high-grade 40/42 chrome concentrate, the next step is selling it to major buyers. Oreways Mining, one of the largest chrome buyers in South Africa, consistently seeks high-quality chrome concentrate for their operations.
Here are a few key factors to consider when selling your product:
- Quality Specifications: Chrome buyers like Oreways typically require a Cr₂O₃ content of 40-42%, with low levels of impurities such as silica (SiO₂) and iron (FeO). Meeting these specifications is essential for securing top prices.
- Price Trends: Keep an eye on the local chrome market trends to time your sales for maximum profitability. The demand for high-grade chrome concentrate, especially in stainless steel production, remains strong, offering favorable market conditions.

Logistics: Efficient transportation
is key to delivering chrome concentrate to buyers
while minimizing costs. Oreways operates on a
Delivered at Place (DAP) model, ensuring the smooth
delivery of products to the specified location.
