What is a double roll break Double roll break is also called double roller series of double roll crusher can be used for finely crushing various high and medium hardness ores and rocks in industrial sectors such as mineral processing chemical industry cement refractory materials abrasives and building materials
Rolls were easy to manufacture to install and to operate in a wide range of applications A robust and reliable design low machine height and an excellent ratio of capacity versus machine mass make double roll crushers DRC still today the preferred choice for many soft to medium hard rock applications in quarries and ore mines

A low grade sample of a double refractory gold ore was obtained from Barrick Gold Strike Two kilograms of the ore was mixed with 850 ml of tap water and ground for an hour in a mild steel rod mill with stainless steel rods 23 rods with a mass of kg to achieve 95% −75 μm 80% passing size P 80 42 μm The slurry was filtered in a
For gold ore operations Polycom HPGR offers several attractive options all of which will help to improve the metallurgy of the gold and significantly improve operating costs Additional options for high pressure grinding roll use in gold ore comminution circuits are illustrated in Figure 11 As indicated by Kapur et al 1992 high
Typically gold is encapsulated or finely disseminated in refractory gold ores and the direct cyanidation is not effective for gold extraction from these ores even after the ore is ground to exceeding small particles Nazari 2017 Corrans and Angove 1991 Especially for sulfide refractory gold ores in order to recover gold many oxidation pretreatment technologies
Optimise crushing efficiency FLS Double Roll and ERC Crushers FLS double roll and ERC crushers offer efficient reliable crushing with low maintenance and optimised wear life Bauxite ore coal overburden Bauxite ore coal overburden Product size 0 to 300 mm 0 to 400 mm Capacity 2 500 to 4 000 tph 4 000 to 6 000 tph
At the moment thiosulfate leaching is the one of the most developed and the only implemented in industry alternative method to cyanidation due to the low toxicity and high efficiency in treatment of preg robbing gold ore Breuer and Jeffrey 2000 Marsden and House 2006 Muir and Aylmore 2005 Nevertheless it still has drawbacks such as complexity of the

A HPGR is principally a horizontally mounted double roll mill equipped with hydraulic pistons on one side pressing against the floating roll the other roll being fixed in the frame conducted on a hard abrasive gold ore will prove that this technology is now ready to challenge conventional circuit design Maximum feed size vs roll
The application of pressure oxidation POX followed by thiosulfate gold leaching is an efficient method used to extract gold from double refractory gold ores containing both sulfide and carbonaceous matter This process is expected to result in high gold recovery rates as it liberates gold from sulfides and eliminates the preg robbing behavior of carbonaceous matter
