Its main activity is open pit mining and processing of copper and copperpyrite ores , biochemical leaching of copper and the associated trade and engineering activities .
Professor Lachezar Tsotsorkov PhD , Chairperson of the Assarel-Medet Supervisory Board , said : “ We were the first company in Bulgaria to begin the mining of ores and minerals , and today Assarel-Medet processes about 13 million tonnes of ore per year , ensuring sustainable development , production and thorough utilisation of minerals at the Assarel deposit .
“ We are ISO certified and work in compliance with the three major international standards for quality management , environment protection and occupational health and safety . We have traditionally been a pioneer in the mining industry with regards to the implementation of new stateof-the-art equipment and new technologies .
“ The Medet Mine ( 1964-1994 ) construction started in 1961 and it was the largest open pit mine in Europe and the third largest in the world for the time . Efficient mining and processing of copper ore with copper grade lower than 0.4 percent was organised here more than 40 years ago for the first time in the world . This is a practice which was later commonly applied in the mining industry , but we were the pioneers .”
