Zamkati
Mtsogoleri (Pb) ndichitsulo chofewa, chosalala komanso chosakhazikika cha tebulo la periodic lomwe lilipo m'chilengedwe.
Kodi zimachokera kuti?
Zambiri mwazitsulozi zimakumbidwa pansi. Komabe, izi sizili choncho, ndiye kuti pali zitsulo zopitilira 60 zomwe zimatha kukhala ndi lead, koma pali zitsulo zitatu zokha zomwe zimagwiritsidwa ntchito kutulutsa lead: galena, cerussite ndi anglesite. Pomaliza, ndikofunikira kunena kuti kugwiritsa ntchito kwakukulu kwa lead ndi kupanga mabatire omwe angathe kutsitsidwanso.
Mchere womwe amatsogolera kwambiri ndi galena, komwe umapezeka ngati lead sulfide. Chifukwa chake, mcherewu umakhala ndi 85% ya lead ndipo ina yonse ndi sulfure. Pali madipoziti a galena ku Germany, Mexico, United States, Spain ndi Australia.
Zowotcha zimagwiritsidwa ntchito kutulutsa mtovu kuchokera ku galena, pomwe miyala imayikidwa ndipo oxide imachepetsedwa mpaka gawo la sulide la lead litasinthidwa kukhala lead oxide ndi sulphate.
Ngati kutsogolera kumayikidwa m'ng'anjo ndi kuyerekezera panthawiyi, zoipitsa zingapo zimamasulidwa: bismuth, arsenic, cadmium, mkuwa, siliva, golide ndi zinc. Pambuyo pakupeza misa yosungunuka m'ng'anjo yomwe imalandira dzina loti ng'anjo yamoto ndi mpweya, sulufule ndi nthunzi, izi zimakwanitsa kusungunula zitsulozo kupatula golide, siliva ndi bismuth. Zinyalala zonse zomwe zimayandama ngati zinyalala zimachotsedwa.
Zowonjezera:
- Kodi mafuta amachokera kuti?
- Kodi aluminium imachokera kuti?
- Kodi chitsulo chimachokera kuti?
- Kodi mkuwa umachokera kuti?
- Kodi golideyo amachokera kuti?
Yendetsani kutsogolo
Pine, laimu, xanthate ndi mafuta a alum amagwiritsidwa ntchito kwambiri. Miyala yamiyala kapena miyala yachitsulo imagwiritsidwa ntchito pophika. Izi zimathandizira kuphika.
Yobwezeretsanso
Komabe, sikuti kutsogolera konse kumachokera ku migodi. 50% yokhayo yomwe ikutenga kutsogolera imachokera kumeneko; zina 50% zimachokera kukonzanso zamagalimoto (mabatire).
