Recycling of Rock-Salt Dust and Brine after Rock-Salt Production

Abstract

This paper concerns the issue of the management and recycling of rock-waste (rock-salt dust in particular), tailings, and brine gener - ated by rock-salt extraction and processing. The author discusses the methods of brine treatment for the needs of further processing. In that context, an option for combined rock-salt dust and salt-mine brine recycling has been developed, with the use of the existing installations and with the objective to obtain evaporated salt for commercial purposes. The paper also mentions other options of rock- salt dust and brine management in one of the salt mines belonging to the KGHM “Polska Miedź” S.A. corporation.
