Mokhoa oa Colorimetric

Mokhoa oa colorimetric o sebelisa karabelo ea li-ion tsa cyanide ka li-reagents tse itseng ho hlahisa sehlahisoa se mebala. Matla a 'mala a lekana le bongata ba li-ion tsa cyanide. Ka mohlala, pampiri ea tlhahlobo ea mahloriso ea cyanide e entsoeng ke Beijing Jinsuokun e itšetlehile ka molao-motheo ona. Pampiri ea teko e na le letšoao le khethollang le sebetsanang le li-ion tsa cyanide mocheso oa kamore ho fetola 'mala. Ka ho bapisa 'mala oa pampiri ea teko ka mor'a ho qoelisoa ka har'a tharollo ea sampole ka' mala o tloaelehileng - karete ea papiso, bongata ba li-ion tsa cyanide tharollong bo ka khethoa kapele. Mokhoa ona o na le melemo ea molumo o monyane, ho nkeha habonolo, bonolo, litšenyehelo tse tlase, le tlhahlobo e potlakileng. E loketse ho lekola bongata ba cyanide litharollong tsa leaching, litharollo tsa tailings, le litharollo tse ling lits'ebetsong tsa tlhahiso ea morafo oa khauta joalo ka heap leaching, tank ea leaching, le ore cyanidation kaofela. Lethathamo le sebetsang la pampiri ea liteko hangata ke 0.01% - 1.0%, e ka fihlelang litlhoko tsa maemo a mangata a tlhahiso ea khauta.
