Yan Wong

Minerals pharmaceutical engineer,30 years pharmaceutical experiments, director of Yantai Fulin Mineral Processing Pharmaceutical Factory.

The company pharmacy factory specializes in all kinds of metal ore, metal oxide ore, non metal ore beneficiation collector, gangue mineral inhibitor, activator, has a number of national invention patents. The independently developed FL series collector has been widely applied to fluorite, barite, feldspar, scheelite beneficiation and reverse flotation of iron ore. Its specific active groups can be combined with floating minerals at room temperature, and the temperature is ≥ 4°C. The process of mineral slurry heating can be avoided and production costs will be greatly reduced.This series of collector has been used by manufacturers in Shandong, Henan, Hebei, Inner Mongolia, Anhui, and Mongolia, Thailand and other places, and has won favorable comments from users. Copper oxide, lead-zinc oxide collector, activator, silica inhibitor, barite inhibitor and calcium carbonate inhibitor are responsible for hundreds of testing tasks for the company and customers every year.
