摘　　要：在某些微生物堆浸矿矿生产工艺中,由于矿石的泥化,孔隙和裂隙分布不均等,常会出现沟流,结块等现象。这样会造成浸出效率不够高,同时也是一种资源的浪费。表面活性剂能有效改善矿石的亲水性和渗透性,有利于矿石和细菌的接触,对提高浸出效率有重要意义。本文主要研究表面活性剂在微生物浸铀中应用现状以及其发展前景。In the production process of some bio-heap leaching, some channel flows and cakings often appear due to argillization of ore, pore and fissure distribution inequality. This will cause low leaching efficiency and it is a waste of resources. Surfactant can effectively improve hydrophilicity and permeability of ore. It is advantageous to the contact of minerals and bacteria and important significance to improve the efficiency of leaching. This paper mainly introduce the application situation and its development prospect of surfactant in uranium bioleaching.
