Recovery of tires allows to significantly reduce the operating costs of equipment. The recovered tires are much cheaper, which makes them an economically advantageous solution for mining companies.
The tests involve foremen and engineers from Kumtor mine and the tire recycling plant in Tokmak. The purpose of the tests is to evaluate the efficiency and safety of recovered tires in real operating conditions.
