The Blockbuster team is pleased to announce the addition of Gamsberg zinc mine to its growing client base, having succesfully used Blockbuster at its sister site, Skorpion zinc mine, since 2002. The Blockbuster software was implemented on site in April 2017 and the African team will be working hand-in-hand with the geologists on site to implement best practise grade control procedures.
Company: Vedanta Zinc International
Description: The Gamsberg zinc mine, in the Northern Cape Province of South Africa, is one of the world’s biggest undeveloped zinc deposits. Construction of the mine started with the groundbreaking ceremony in July 2015. First production from the mine is expected by 2017. The Gamsberg-Skorpion integrated project in Gamsberg, South Africa, includes the development of an open-pit zinc mine, concentrator plant and associated infrastructure, and the conversion of the Skorpion zinc refinery in Namibia. Upon completion, the project will make South Africa one of the most important suppliers of refined zinc worldwide.
Reserves: As of 2016, the Gamsberg Project has reserves and resources of 214Mt with the potential to produce 450-500ktpa of zinc in concentrate.
Mining Method: Conventional open-pit mining, including drilling and blasting followed by loading and hauling, will be used at the Gamsberg mine. The mined ore will be transported by haul trucks to the 9.07Mtpa primary crusher located adjacent to the open pit. The crushed ore will be stockpiled before conveying through a reclaim conveyor to the milling circuit that will consist of a semi-autogenous grinding (SAG) mill, a ball mill, and a cyclone unit to reduce the ore material to a size appropriate for flotation. After passing through a variety of flotation modules, the zinc concentrate is produced.
