Metinvest's Central GOK is the first in Ukraine to equip the beneficiation area with KDF-90 ceramic filters. Installation of new vacuum filters is part of a large-scale project of the enterprise for the production of pellets based on direct reduction of iron technology. Investments in modernization amounted to 5 million US dollars. The new equipment allows reducing the cost of iron ore processing. The operation of the filters is supported by a stand-alone unit with the pump, which ensures energy savings of 640 kWh vs. the dismantled DOO-100 fabric filters. KDF-90 can be supplied with a thicker mass for drying, which reduces the consumption of process water. Ceramic consumables require replacement every year and a half, while fabric replacement was required every month.

Ceramic filter elements are designed to produce 80 to 120 tons of concentrate per hour. For comparison, the old equipment production rate was 30-40 tons per hour. The new filters will be part of the technological process set up to produce a concentrate with Fe 70.5%.
