Lead

Lead is easily remelted and refined and as such has the highest recycling rate of all industrial metals in the world. For this reason secondary or recycled lead now represents a significant portion of the lead market.

Lead Softening and Refining

Lead - Secondary Smelting

Like all technologies, it is the way that you use them that is critical to the economic and technical success of a project. The benefits of oxy-fuel are now well-accepted and proven in industry. The point is; If you are going to adopt a new technology, you want to get the maximum benefit that it has to offer. There is no substitute for knowledge and experience.

We have put our knowledge of gas flow control systems, burner design and the ability to engineer systems of the highest quality together with our deep understanding of the melting process. Our approach is to make a detailed study of an existing furnace that a customer is considering to convert to oxy-fuel and predicting the results of a conversion using the latest technology. Based on these results, we can specify, build, install and commission a system that is tailor-made for that particular furnace and that will ensure that you get the maximum benefits from oxy-fuel.

Main benefits of the oxy-fuel technology:

  • Increased melt rates.
  • Energy savings.
  • Reduced emissions.
  • Increased casting yield

Lead - Lead Softening and Refining


Lead softening is a refining operation where the objective is to remove impurities from the recovered lead. The main impurities are tin, arsenic and antimony. Traditionally the softening and refining process uses chemical products to remove the impurities. The oxygen technology for lead softening and refining uses a mixture of air with pure oxygen that is bubbled through molten lead to remove the impurities by selective oxidation.

Main benefits of the oxy-air refining technology:
  • Reduced softening times.
  • Increased productivity.
  • Reduced use of chemicals
