But the HYPERLINK /dict_result.aspx?searchword=%e5%93%81%e4%bd%8damp;tjType=sentenceamp;styleamp;t=quality quality of manganese majority minerals is low, HYPERLINK /dict_result.aspx?searchword=%e5%b9%b3%e5%9d%87amp;tjType=sentenceamp;styleamp;t=the%2Baverage the average quality is about 22%, the quality level is usually poor, there are no rich minerals of international HYPERLINK /dict_result.aspx?searchword=%e5%95%86%e5%93%81amp;tjType=sentenceamp;styleamp;t=commercial commercial HYPERLINK /dict_result.aspx?searchword=%e5%95%86%e5%93%81amp;tjType=sentenceamp;styleamp;t=commodity commodity. The HYPERLINK /dict_result.aspx?searchword=%e8%8f%b1%e9%94%b0%e7%9f%bfamp;tjType=sentenceamp;styleamp;t=rhodochrosite rhodochrosite is the majority of manganese mineral proved reserves. The quality of this type is low, the average quality is under 20% , the level of HYPERLINK /dict_result.aspx?searchword=%e6%9d%82%e8%b4%a8amp;tjType=sentenceamp;styleamp;t=impurities impurities quantity is high, the quantity of Mn minerals can be increased limited(usually increased from 3% to5%),the most is not suitable for metallurgy and production. The resource of manganese in Guizhou is the third in China which the most is HYPERLINK /dict_result.aspx?searchword=%e8%8f%b1%e9%94%b0%e7%9f%bfamp;tjType=sentenceamp;styleamp;t=rhodochrosite rhodochrosite, the HYPERLINK /dict_result.aspx?searchword=%e8%8f%b1%e9%94%b0%e7%9f%bfamp;tjType=sentenceamp;styleamp;t=rhodochrosite rhodochrosite quantity is 83.798 million ton which occupies 98.64% of th
