Abstract
U ovom radu prikazani su rezultati ispitivanja koncentracije kvarcnog pijeska postupcima gravitacijske koncentracije (koncentracijskim stolom i spiralnim žlijebom – Humphreysovom spiralom). Cilj rada je ispitati mogućnost koncentracije kvarcnog pijeska gravitacijskom koncentracijom uz postizanje kvalitete koncentrata koji zadovoljava uvjete kvalitete za plasiranje na tržište. Provedena su dva seta ispitivanja na koncentracijskom stolu pri različitim nagibima koncentracijskog stola (3°, 6° i 9°), jedan s ciljem postizanja što veće kvalitete koncentrata i jedan s ciljem postizanja što većeg masenog iskorištenja. Ukupno je napravljeno ispitivanje na 6 uzoraka kvarcnog pijeska na koncentracijskom stolu. Na spiralnom žlijebu provedena su 4 ispitivanja pri različito podešenim parametrima (otvori ispusta za tešku frakciju, gustoća suspenzije i protok ispirne vode). Uspoređeni su tehnološki pokazatelji uspješnosti koncentracije pojedinih ispitivanja, odnosno postignuta kvaliteta koncentrata utvrđena kemijskom analizom uspoređena je s uvjetima kvalitete za plasiranje na tržište.
Abstract (english)
This thesis presents the results of concentration tests carried out on quartz sand using gravity concentration methods (shaking table and spiral concentrator – Humphreys spiral). The aim of the thesis is to examine the possibility of concetrating quartz sand using gravity concentration methods to achieve concentrate quality that satisfies the quality requirements of the marketplace. Two sets of tests were carried out using a shaking table at different shaking table inclination (3°, 6° i 9°), one set aiming to achieve higher concentrate quality and the other set aiming to achieve higher recovery. Tests were carried out on 6 samples of quartz sand using shaking the table. Using a spiral concentrator, 4 tests were carried out with different parameter (heavies openings, slurry density and wash water flow) adjustment. The concentration efficiency indicators of each test were compared i.e. achieved concentrate grades determined by chemical analysis were compared with the quality requirements for market placement.
