前言福建省连城兰桥锰矿属于淋滤型氧化锰矿床。此类型矿床为该省目前锰矿的主要工业类型。矿体规模较小,质量较佳,但有一部分贫矿和粉矿必须经过选矿进行选别富集后方可利用,因此根据该类型矿石特性采用切实可行、流程简单、收效快的选别流程以期达到充分利用矿产资源、提高经济效益的目的有重要意义。笔者通过该类型贫锰矿石特性的初步研究,浅谈该类型矿石特性对选矿工艺的影响。由于水平不高,谬误之处较多,恳请指教。 1.矿石物质组成特征矿石中有回收价值的矿物主要为软锰矿,硬锰矿等锰的氧化物。锰矿物大多以隐
Preface Fujian Liancheng Langqiao manganese ore belongs to the leaching-type manganese oxide deposit. This type of deposit is currently the province’s major manganese ore industry. Due to its small size and good quality, some lean ore and fines ore have to be beneficiated by beneficiation before they can be used. Therefore, according to the characteristics of this type of ore, feasible and simple process with quick efficiency To achieve the full use of mineral resources, improve economic efficiency purposes of great significance. Through the preliminary study of the characteristics of this type of poor manganese ore, the author discusses the influence of the characteristics of this type of ore on beneficiation process. As the level is not high, more mistakes, please enlighten. 1. Ore composition characteristics of the minerals in the ore recovery value of mainly pyrolusite, hard manganese and other manganese oxide. Manganese minerals are mostly hidden
