Ball Milling an overview ScienceDirect TopicsBall milling technique using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys In fact ball milling process is not new and dates back to more than 150 years It has been used in size comminutions of ore mineral dressing preparing talc powders and many . RECYCLING TECHNOLOGY FOR GOLD CONTAINING TAILINGS as a CF in the flotation of gold containing tailings For studies the original tailings were reground in a laboratory ball mill 40ML 000PS Russia up to 95 % of the class 0 074 mm Sedimentation analysis of the tailings was performed with the use of an FSKh 6K photometric sedimentometer Russia. Gold Ore Milling Input Size Output SizeGold Ore Milling Input Size Output Size Each year global gold mining adds approximately 2 500 3 000 tonnes to the overall above ground stock of gold production has shown an upward trend in recent years this is likely to level off in coming estimating the amount of gold still within the ground is no easy task and this estimate may change in response to several
