Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method for processing lead glass and electronic waste by crushing and mixing them, then melting the mixture with certain additives, and reducing lead oxide to metallic lead. The process separates the materials into a metallic phase and a glass phase, allowing for efficient recovery of lead and safe handling of waste glass.

Use CasesContent extracted from patent full text and abstract with AI.

  • Recycling of discarded cathode ray tubes and other leaded glass products
  • Processing and recovery of valuable metals from electronic waste
  • Safe disposal and reuse of hazardous lead-containing glass
  • Industrial treatment of mixed electronic and glass waste in recycling plants

BenefitsContent extracted from patent full text and abstract with AI.

  • Enables recovery of valuable metals like lead from waste streams
  • Reduces environmental impact of hazardous electronic and glass waste
  • Transforms hazardous waste into usable materials (metal and glass)
  • Supports the circular economy and sustainable material management
  • Improves safety and efficiency in recycling operations by combining processes
