At Metinvest's Northern GOK, specialists from the Hannivskyi Quarry are working on the improvement of production and proposing operational improvements to meet key performance indicators and reduce production costs.

The employees of the integrated GOK are systematically examine equipment condition, production processes and the possibility of improving their work to ensure that production tasks are completed efficiently and quickly.

"In August-September, we have already reached a $1.5 per ton of ore cost reduction. We achieved this by revising our quarry logistics, reducing the distance of rock mass transportation, optimizing equipment operation, and taking measures to reduce the cost of drilling and blasting operations. We are still keeping on moving: we continue to search for energy-saving solutions, develop optimal transport links, and promising areas for mining operations. "We are currently conducting tests to expand the production well network, which will allow us to save even more on drilling and blasting operations," said Yurii STULII, head of the Northern GOK Hannivskyi Quarry.

Miners of Hannivskyi Quarry have a special approach to energy efficiency as well. For quite some time, the specialists have been studying the experience of the Northern GOK Pershotravnevyi Quarry and explored the operation of equipment. Currently, they are thinking through how to apply their coworkers' approaches and develop with Hannivskyi Quarry team their own effective measures to reduce the cost of iron ore raw materials.

The miners are currently mining in the southern and central parts of the quarry, where the stripping ratio is the lowest. The ore having a magnetic iron content of 25.0% and 67.0% concentratability is transported to the ore beneficiation plant to produce A1 grade concentrate.
