psilomelane

psilomelane

1. The main silver-bearing minerals were psilomelane, pyrolusite, limonite, galena, pyrite and sphalerite.

主要载银矿物有硬锰矿、软锰矿、褐铁矿、方铅矿、黄铁矿和闪锌矿。

2. The compositions of major elements show that the psilomelane is rich in K and poor in Mn, but pyrolusite is rich in Mn and poor in K.

常量元素含量表明：硬锰矿富钾、贫锰，软锰矿贫钾、富锰。

3. Main metallic minerals in the manganese-silver concentrate were psilomelane, pyrolusite, pyrite, limonite, and a few arsenopyrite, hematite and sphalerite.

该锰银精矿的主要金属矿物为硬锰矿、软锰矿、黄铁矿、褐铁矿、少量毒砂、赤铁矿和闪锌矿；

4. It is studied that most of tungsten in ore occurs in secondary psilomelane in the form of adsor-bed ions.

通过研究得出，矿石中钨绝大部分是呈离子吸附形式赋存于次生硬锰矿中。

5. Silver occurred in form of minerals in the cryptomelane,coronadite,psilomelane with minor silver absorbed in the manganese minerals.

银主要以独立矿物和离子吸附状态的形式赋存于地表锰铅矿和锰钾矿中;

6. The mineral components of nodules are mainly pyrolusite, psilomelane and limonite.

锰结核主要由硬锰矿、软锰矿、褐铁矿构成。
