The beneficiation of ore at this facility is carried out by wet separation by washing and classification, whereby tailings separation sludge is separated. Sludge is deposited in the reservoir at the dam, where it settles, and the clean overflow water goes into regular waterways. Tests have shown that this water has the quality of well water, since it is not chemically polluted.
System for collecting used engine and hydraulic oil and oil separator
On the industrial platform of the Central mining sites, a service-drive workshop was built for servicing and intermediate repairs of machines and plants. In the process of servicing and repair, the oil in the machines is changed, and the old used oil appears as industrial waste. In order to prevent the old used oil from being thrown on open surfaces and waterways, a system was built for collecting used oil with tanks and a transfer plant. Collected oil from the tank is sent to the Oil Refinery in Modriča for recycling. When servicing machines, despite the built-in system for collecting old oil, a small percentage of oil is spilled during replacement. In order to collect the spilled used oil and prevent it from going into the Tomruci stream when washing the service platform, an oil separator was built. The oil separator was installed before the service platform drainage channel enters the Tomruci stream. In the separator, oils are extracted from the waste water and transferred to a tank, from where they are taken together with the used oil to the Modriča Oil Refinery for recycling.
