We produce rock salt from underground mines using both drill-and-blast and continuous mining techniques. Our rock salt The drill-and-blast mining method begins by cutting into the rock salt face using specialized equipment. We then drill into large rocks. Fro
Rock salt is extracted from the deposits with classical mining methods by rock cutting either mechanically or by blasting. Spoils are delivered to the processing plant to be subjected to mechan- ical processing (crushing, sieving, dedusting etc.),.
Salt, i.e. sodium chloride, is a mineral that naturally occurs in our seas and underground deposits. It is an ionic chemical There are three types of salt extraction: solar evaporation, rock salt mining and solution mining. Each one Solar evaporation is proba
