硅錳合金是由錳、硅、鐵及少量碳和其它元素組成的合金，用途廣、產(chǎn)量大。那么其所需的錳礦石又是如何破碎生產(chǎn)的呢？

硅錳合金是由錳、硅、鐵及少量碳和其它元素組成的合金，是一種用途較廣、產(chǎn)量較大的鐵合金。錳硅合金是煉鋼常用的復(fù)合脫氧劑，又是生產(chǎn)中低碳錳鐵和電硅熱法生產(chǎn)金屬錳的還原劑。

生產(chǎn)錳硅合金的原料有錳礦、富錳渣、硅石、焦炭、白云石（或石灰石）、螢石。生產(chǎn)錳硅合金可使用一種錳礦或幾種錳礦（包括富錳渣）的混合礦。由于錳硅合金要求鐵、磷含量比高碳錳鐵低，故要求冶煉錳硅合金的錳礦有更高的錳鐵比和錳磷比。所用的錳礦含錳越高，各項(xiàng)指標(biāo)越好。

錳礦粒度：10 mm~80 mm，小于10 mm的不大于10%；②對焦炭的要求：應(yīng)符合冶金焦條件，固定碳≥84%，灰分≤14%;粒度要求5 mm~25 mm。螢石 中的CaF2≥70%，粒度5 mm~40 mm。對原料的要求與電爐容量大小有關(guān)。

硅錳合金是在礦熱爐中用炭同時(shí)還原錳礦石（包括富錳渣）和硅石中的氧化錳和二氧化硅而煉制生產(chǎn)的。錳硅合金的生產(chǎn)在礦熱爐內(nèi)進(jìn)行，使用碳質(zhì)還原劑、錳礦石、富錳渣、燒結(jié)錳礦、焙燒錳礦和硅石作原料，石灰、白云石、螢石等作熔劑在電爐內(nèi)連續(xù)生產(chǎn)。  

錳在自然界分布很廣，幾乎各種礦石及硅酸鹽的巖石中均含有錳。錳礦最常見的是無水和含水的氧化錳和碳酸錳，現(xiàn)已知的錳礦物有150種，但含錳最高，能大量富集形成有經(jīng)濟(jì)價(jià)值的錳礦物卻不過5-6種，其中最重要、最有經(jīng)濟(jì)價(jià)值的是軟錳礦和硬錳礦，另外還有水錳礦、褐錳礦、黑錳礦、菱錳礦等。這些礦物中錳的含量可達(dá)50～70% 左右，是錳的重要工業(yè)礦物.

常見的錳礦選礦方法有哪些?
1、洗礦篩分法 2、重選法 3、強(qiáng)磁選法 4、重選-磁選法 5、強(qiáng)磁選-浮選法 6、浸出法 7、火法富集法
錳礦石火法富集法是一種處理高磷、高鐵難選貧錳礦石的方法，一般稱之為富錳渣法，主要利用錳、磷、鐵還原溫度的不同，在高爐或電爐中控制其溫度來選擇性分離錳、磷、鐵。碳酸錳礦石選礦方法大多采用強(qiáng)磁選、重介質(zhì)選礦法和浮選法等。氧化錳礦石以重選法為主，多采用洗礦－重選工藝流程或洗礦－還原焙燒磁選－重選工藝流程。
 
錳礦的開采方法有哪些?
沉積型碳酸錳礦石中的錳礦物主要有菱錳礦、鈣菱錳礦、含錳方解石和菱錳鐵礦等；脈石礦物包括硅酸鹽和碳酸鹽礦物，常伴生硫和鐵等雜質(zhì)。一般有（1）露天開采 （2）爆破風(fēng)化預(yù)先松動水采法等方法。
