Xinhai Mining nears completion of 1.5 Mt/y copper flotation plant in Kazakhstan
Shandong Xinhai Mining's 1.5 million tonnes per year sulphide-copper flotation plant in Kazakhstan has entered the equipment installation and commissioning phase, with civil works past the halfway mark and all major equipment foundations accepted. Delivered under a full EPC+M+O contract, the plant treats ore averaging 0.86% copper and is designed for a 22% copper concentrate grade at 90% recovery, processing 5,000 tonnes per day over 300 operating days. Work started in October 2025, resumed in April 2026 after winter, and is scheduled for civil completion by end-September and full commissioning by year-end. Onstream, it will recover roughly 11,600 tonnes of copper metal annually.
