Ke one oka gula

ʻO nā Gold Concentrates a mākou e kūʻai ai:

Kiekie Arsenic Gold Concentrate

ʻ Omaki gula

ʻO nā ores kahi i loaʻa ai ke gula i loko o ka hoʻohui kemika me nā mea ʻē aʻe. ʻO lākou ka calaverite, sylvanite, nagyagite, petzite a me krennerite.
Kona Gula
Hoʻokumu ʻia nā concentrates gula ma nā ʻano ʻelua. ʻO ka mua ma o ka panning gula (a i ʻole nā ​​ʻenehana ʻē aʻe e hoʻohana ana i ka hoʻokaʻawale gravity). I ka wā e pani ai i ke gula, ʻo ka pahuhopu ke hoʻokaʻawale i nā ʻāpana lepo mai nā ʻāpana gula kaumaha. I ka hapanui o nā hihia, ʻaʻole wale ke gula ka mea kaumaha i loko o ka pā. ʻO kēia hopena o ke kaʻina hana panning, ʻo ia nā ʻāpana gula - pono e kānana lima ʻia e unuhi i nā ʻāpana gula. He hao ka nui o ka concentrates gula, no laila ua ʻike ʻia lākou he "one ʻeleʻele."
Hana ʻia nā ʻāpana gula ma ka wili ʻana i ka ʻiʻa, quartz, a i ʻole nā ​​​​ʻano pōhaku waiwai ʻē aʻe i ke one. ʻOi aku ka wikiwiki a me ka maʻalahi o kēia kaʻina hana ma mua o ka panning, akā ʻo ka tradeoff kahi huahana hope loa i emi iho ke gula "concentrated" i loko. ʻO ka lepo uku i hui pū ʻia me nā pahu panning a i ʻole ke kūʻai ʻia aku i mea hoʻomanaʻo ma nā kūlanakauhale wili gula maʻamau mai kēia ʻano wili.

Wehe Gula

ʻO ka ʻili gula e pili ana i nā kaʻina hana e pono ai e unuhi i ke gula mai kāna ores. Pono paha kēia i ka hui pū ʻana o ka comminution, ka hana mineral, hydrometallurgical, a me nā kaʻina pyrometallurgical e hana ʻia ma luna o ka ʻai.
Ua loaʻa mua ka ʻeli gula mai nā ʻaila alluvium e nā ʻenehana e pili ana i ka mining placer e like me ka panning gula maʻalahi a me ka sluicing, ka hopena o ka hoʻihoʻi pololei ʻana i nā nuggets gula liʻiliʻi a me nā ʻōpala. ʻO nā ʻenehana hoʻoheheʻe placer mai ka waena a i ka hopena o ke kenekulia 20 ka mea maʻamau i hana ʻia e nā mea miners akamai. Ua hoʻohana nui ʻia ka mining hydraulic i ka holo gula o Kaleponi, a ua komo i ka wāwahi ʻana i nā waihona alluvial me nā pahu wai kiʻekiʻe. Ua hoʻokumu ʻia nā ʻano pōhaku paʻa i ke kumu o ka hapa nui o nā hana hoʻihoʻi gula ʻoihana mai ka waena o ke kenekulia 20 kahi i hoʻohana ʻia ai nā ʻenehana mining lua a i ʻole lalo.
I ka wā e ʻeli ʻia ai ka ʻai, hiki ke mālama ʻia ma ke ʻano he ʻala holoʻokoʻa me ka hoʻohana ʻana i ka hoʻolei ʻana a i ʻole nā ​​hana leaching puʻu. He ʻano maʻamau kēia o nā waihona haʻahaʻa, oxide. ʻO ka mea maʻamau, e ʻoki ʻia a hoʻopaʻa ʻia ka ʻaila ma mua o ka hoʻopaʻa ʻana i ka puʻu. ʻO nā ʻala kiʻekiʻe a me nā ores kū i ka cyanide leaching ma nā ʻāpana ʻāpana nui, pono e hana hou i mea e hoʻihoʻi ai i nā waiwai gula. Hiki i nā ʻenehana kaʻina hana ke komo i ka wili ʻana, ka noʻonoʻo ʻana, ka ʻala ʻana, a me ke kaomi ʻana ma mua o ka cyanidation.
