The invention relates to a crude bismuth metal recovery technology which adopts wet process and pyrogenic process craft to recover the mental. It first dose water quenching, ball milling, extracting, scouring and filtering to the crude bismuth alloy to obtain the antimony lead skim and leaching solution; the antimony lead skim returns to the pyrogenic process system and then to the lead smelt system; it uses spongy copper to displace the Au and Ag of the leaching solution to produce the gold silver earth which returns to the noble metal smelting system; the liquid after displacing the gold silver earth dose hydrolytic precipitation bismuth and uses limestone and water to inactive it to pH3-3.5, it filters the solution to obtain the bismuth oxide chloride and obtains the crude bismuth by smelting and then obtains the purified bismuth; it uses iron slag to displace the Cu to produce the spongy copper; adding limestone in the liquid after depositing Cu to inactive it and discharges it. |
