Derrick brings fine screening technology to Metalloinvest
Derrick® Corporation announced the introduction of its new SuperStack® vibratory screening equipment to Metalloinvest’s Mikhailovsky GOK beneficiation plant in the Kursk region of Russia. The eight-deck SuperStack offers a significantly higher production capacity than conventional screening equipment in a small footprint, while also offering increased quality of iron ore concentrate.
The first phase of the project was launched at the Mikhailovsky GOK beneficiation plant during an official ceremony. During the first stage of the project, Derrick fine screening technology was introduced at four sections of the beneficiation plant. The design, supply and installation of the equipment, adjustments, and commissioning took place within a short period of just one year. The capital expenditures for the first stage exceeded US$ 18.5 million.
On 3 September 2019, an agreement was signed with Thrane Teknikk to supply Derrick equipment for the second stage of the project: construction of a new building for beneficiation of concentrate at the beneficiation plant. As a result of the successful first stage implementation, the fine screening section is projected to produce over 3.7 million tons of iron ore concentrate, with iron content increasing to 67 % compared with the previous 65.1 %. The second stage of the project, launched in August 2019, will see construction of a new building for beneficiation of concentrate using high-quality Derrick equipment. As a result of the second stage, production of 16.9 million tons of high-quality concentrate with an iron content of 68.7 % expected in 2022. The construction of the new beneficiation building and modernization of production will enable the processing of complex ores having a higher iron content and will reduce overburden and production costs. Investments in the second stage are projected at more than US$ 185 million.
