Zimbabwe 700t/d rock gold ore dressing plant is the largest ore dressing plant designed and completed by Xinhai. In order to achieve zero waste water discharge, the overflow water from the thickener and the filtrate from filter press will be returned to the production cycle. Xinhai helps lower total cost of ownership as well as reduces operating costs so customers get a greater return on their investment.http://www.xinhaimining.com/en/news_text_7_127.html?fb_visits | Xinhai Mining Machinery Co.,
