ʻO nā mea ʻaʻahu ʻaʻahu gula he hui mechanical kūikawā i hoʻohana ʻia e unuhi i ke gula mai ka ʻai gula, ʻoi aku ka nui o ka ʻohi ʻana, wili, grading, flotation a me nā mea hana ʻē aʻe. Hoʻolālā ʻia kāna kaʻina hana no nā ʻano like ʻole o ka vein gold ore, placer gold ore, a me nā mea ʻē aʻe, a ua hoʻokaʻawale ʻia nā minela ma o nā kaʻina hana e like me ka ʻoki ʻana, ka wili ʻana, ka hoʻokaʻawale ʻana i ka gravity a me ka flotation. Ma kahi o 80% o nā mea kanu koho gula e hoʻohana i ka flotation.

ʻO nā mea hana koʻikoʻi e pili ana i ka jaw crusher, ball mill, classifier, chute and flotation machine, etc. I waena o lākou, hoʻohana nui ʻia ka jaw crusher i ka ʻoki ʻia ʻana o ka oka ma muli o kona ʻano maʻalahi a me ka mālama pono. Hoʻohana ka hoʻokaʻawale ʻana i ka ʻumekaumaha i ka ʻokoʻa o ka nui o ka minerala, a ʻo nā mea hoʻohana maʻamau e pili ana i ka chute, ka papa haʻalulu, etc.; ʻO ke ala cyanidation e unuhi i ke gula ma o ka leaching, holoi a me nā hana ʻē aʻe. ʻO ka hui pū ʻana o ka centrifuge a me ka papa haʻalulu hiki ke hoʻihoʻi maikaʻi i ke gula, a hiki ke mālama ʻia ka ʻeleʻele haʻahaʻa haʻahaʻa e ke kaʻina leaching puʻu.

Hoʻohana nui ka hoʻoheheʻe gula i ka hoʻoheheʻe ʻia e hana i ke gula hui ʻia a i ʻole ke gula paʻa. ʻO ka hui pū ʻana o nā mea hana a me ke kaʻina hana e ʻike ai i ka hoʻololi maikaʻi ʻana mai ka oka i ke gula paʻa. Hāʻawi ʻia kekahi mau lako e TSX pale, Tianjin, Kina.
