Metinvest Group’s Ingulets mining and processing plant of, a new route of the ore cyclic-flow technology complex was put into operation. This is one of the largest mining projects in the company over the past decade. Metinvest invested about USD 50 million in the construction of the complex. The CPT complex is located in a quarry, is a system of underground and surface conveyors and consists of two routes - the new East and the existing West. Ore is mined in the face, loaded by excavators into dump trucks, which bring it to the transfer point, where the ore is crushed into large pieces. After crushing, the system of underground conveyors of the Eastern and Western tracts delivers the ore to the surface of the quarry, where it undergoes medium and fine crushing, and then goes for concentration. The ore covers the path from 300-meter depth to the surface of the open pit in 15 minutes.The construction of the complex took six years. During this time, capital mining and construction works were carried out, the main technological and auxiliary equipment was installed. All work is automated - this allows you to control absolutely all parameters of the equipment. Also, an automated aspiration unit is installed at the central heating center, which cleans the air from dust.The launch of the cycle-flow technology complex allows for faster delivery of ore from the lower horizons of the quarry and reduces the use of dump trucks. The dump truck route is reduced by 10%, which makes it possible to reduce the cost of transporting ore.In addition, due to environmentally friendly and economical conveyor transport in the quarry, the technologic load on the environment, operating and maintenance costs will be reduced.
