Because of detection limitation, the gold particles are not found independently in pyrite, scheelite, quartz, and other minerals. So it is believed that submicroscopic gold can be found in gold-bearing minerals as micro-inclusions or isomorphous atoms.

由于受检测手段所限，在含金黄铁矿、白钨矿、石英等矿物中未发现独立金颗粒，所以寨上金矿次显微金呈微包裹体形式存在于载金矿物中或呈类质同象替代的原子形式存在。

Because of detection limit the gold particles are not found independently in pyrite scheelite quartz and other minerals. So it is believed that submicroscopic gold are occurred in gold-bearing minerals as micro-inclusions or isomorphous atoms.

受检测手段所限在含金黄铁矿、白钨矿、石英等矿物中未发现独立金颗粒，所以我们倾向于寨上金矿次显微金呈微包裹体形式存在于载金矿物中或呈类质同象替代的原子形式存在。

The additive can destroy the structure of the high-alumina iron ore and create conditions for the Al-Fe separation, which is especially suitable for the Al-Fe separation of the high-alumina iron ore when iron ore and alumina ore are embedded by fine particles or alumina exists in isomorphous form in iron mineral.

所用添加剂能破坏高铝铁矿石的结构，为铝铁分离创造条件，特别适合于铁矿物和铝矿物以微细粒嵌布，或铝以类质同象形式存在于铁矿物中的高铝铁矿石的铝铁分离。
