Project

By using HPY Technology's ore sorting machines to pre-reject waste rock, the company can now mine resources in areas that were previously considered low-grade and burdened with an excess of waste rock. Early sorting of waste rock in the process enables these areas within the excavation site to be mined, allowing Yunnan Tin Group to make better use of available resources. Yunnan Tin and HPY Technology have agreed to continue collaborating on ways to incorporate ore sorting to enhance the tin industrial chain and fully utilize waste rock by recovering tin-copper ore from the waste rock piles.

Economic Benefits

According to data from Datun Tin Mine: with One Unit of HPY Classic Series Ore Sorting Machine

  • 100,000 tons of pre-rejected waste rock per year
  • Reduced mineral processing costs of 1.4 million USD per year
  • Reduced tailings disposal costs of 214,000 USD per year
  • Reduced tailings pond expansion cost of 370,000 USD per year
  • Annual economic benefits of 2 million USD
