Northern Iron Ore Enrichment Plant (Northern Iron Ore Enrichment Plant, Kryvyi Rih, Dnipro region), part of Metinvest Group, has upgraded its pumping equipment for UAH 3.2 million to ensure the quality of iron ore concentrate.
According to the plant’s information on Thursday, a vacuum pump was replaced at the dewatering section of the ore dressing plant (ODP) No. 2 at Northern GOK. The new equipment will ensure the required moisture content in the iron ore concentrate.
It is specified that VNN2-300 vacuum pumps are used in the concentrate production process at ROF-2. They are used to create a vacuum in the overall system during concentrate dehydration. In total, the plant has 18 units of such equipment, of which 17 are constantly involved in the technological process and one is a backup. Due to the wear and tear of one of the vacuum pumps, the plant dismantled it and installed new similar equipment.
Andrian Myshko, head of the ore dressing section of ROF-2, explained that the operation of a certain amount of pumping equipment affects the quality of products, namely the percentage of moisture in the dehydrated product. A decrease in the vacuum in the collector due to the absence or malfunction of equipment leads to an increase in the percentage of moisture in the concentrate, which, in turn, requires an increase in bentonite consumption in the production of pellets in the pelletizing shop No. 2.
“The vacuum pump that we replaced has effectively served its useful life, even with a surplus. It was replaced by a new one of the same modification. With it, we will ensure the nominal performance and the required vacuum level in the system, which will reduce the total number of vacuum pumps operating in the process and reduce electricity consumption,” the site manager said, as quoted by the press service.
In 2024, two more units of pumping equipment are planned to be replaced at Northern GOK’s ore dressing plant No. 2.
