The Emax is an entirely new type of ball mill which was specifically designed by RETSCH for high energy milling. The impressive speed of 2,000 min-1, so far unrivaled in a ball mill, in combination with the special grinding jar design generates a vast amount of size reduction energy. Thanks to the new liquid cooling system, excess thermal

Gold in the placer is usually gold of elementary substance with its high monomer disintegrate degree. They are generally the shapes of pulley, piece or branch with its granularity of 0.5-2mm. So gravity beneficiation-amalgamator separation can gain excellent beneficiation efficiency. The big waste gangue in the gold ore should be screened before the gravity separation to help prevent the

May 09, 2020 Before retorting we used to press the amalgam sponge in a lever pipe press and the free mercury would run out the bottom into a bowl. leaving a grey crumbly cylinder of amalgam. The retort itself was pretty simple - another bit of pipe with a threaded cap. The pressed cylinder was loaded into the pipe & the cap screwed on
