Abstract: Basalt type copper deposit is a kind of unconventional cooper resource,has great resources potentialities.By means of using optical microscope,scanning electron microscope,X-ray diffraction and energy dispersive spectrometer,used of integrated basalt type cooper test samples from Weining,western Guizhou,detailed processing mineralogy study has been described in this paper.The results showed that the cooper is basalt type,Cu content of 2.2%;the major copper minerals are native copper,chrysocolla and chalcocite,4% of the total.Gangue minerals are mainly laumontite,quartz and albite.After calculation,the relative distribution of the cooper in the cooper minerals reached 42.28%,chalcocite,18.11%,chrysocolla,39.61%.The floatability of the native cooper and chalcocite is better than chrysocolla,which with fine granularity,complex disseminated feature and difficult dissociation.So,ore dressing of this basalt type copper should focus on the native cooper and chalcocite,part of the chrysocolla is difficult to recycle through physical sorting,it is reasonable and receivable waste.
