广西是我国锰矿资源及产量较多的一个省区,已探明的工业储量,约占全国总量的三分之一强,其中氧化矿又占广西储量的五分之一。氧化锰大部分为中小型的堆积锰矿,除少数是原生锰帽型外,大都是次生堆积型的淋滤型残坡积矿床或风化堆积型矿床,围岩大都是矽质粘土,脉石矿物为矽质页岩、粘土、石英等。用水采和机采两种方法开采,采矿中混入一定量的围岩。这类锰矿的特征是:分布广,埋藏浅,便
Guangxi is a province with more manganese resources and more output in our country. Proven industrial reserves account for about one third of the national total, and oxide ore accounts for one fifth of Guangxi’s reserves. Manganese oxide is mostly small and medium-sized stacked manganese ore, except for a few of the original manganese hat type, mostly secondary accumulation type leaching-type residual slope deposits or weathered accumulation deposit, the surrounding rock mostly siliceous clay, gangue Minerals for the silicon shale, clay, quartz and so on. Water mining and mining two methods of mining, mining mixed with a certain amount of rock. Such manganese ore is characterized by: wide distribution, buried shallow, then
