DELKOR thickeners ordered for tailings treatment modernization in Ukraine

Successful operation of recently installed DELKOR thickeners triggers further order from Ukraine.

A recent order for four high-rate thickeners highlights the increasing demand from Ukrainian mining and industrial operations for DELKOR liquid/solid separation technologies. The order, received earlier in the year from Engineering Dobersek, a leading engineering company and EPC contractor in the region, was placed as a result of the successful supply of 3 similar DELKOR high-rate thickeners, also to Engineering Dobersek, for a mining and processing plant’s modernized slurry thickening complex. See here ( for an article on this previous project.

The 62 m-diameter thickener mechanisms will be used to thicken iron ore tailings, prior to being pumped to settling ponds. The thickeners offer a particularly high throughput of up to 22,500 m³/h thanks to the DELKOR proprietary feed well technology and decade long process expertise.

The high-rate thickeners were ordered as part of the modernization of the iron ore tailings facility, with the new process waste thickening complex being the second of its kind to be established in Ukraine - the first having been the aforementioned three thickener project. The greenfield plant aims at decreasing environmental impact and costs by lowering energy consumption and water usage.

Andrey Yaschinsky, TAKRAF Eurasia: Director General, had this to say regarding the recent order: “TAKRAF Group’s Russia and India offices collaborated closely on concluding the contract, with engineering, fabrication and supply of the equipment being performed from DELKOR’s workshop and fabrication facility in India. Both offices’ teams are to be commended on their close collaboration and commitment. As a repeat order from Engineering Dobersek, this project is testimony to the trust our client’s place in our DELKOR liquid/solid separation technology and is a proud addition to our already long reference list and expanding presence in Ukraine.”
