Kuphwanyidwa kwa chikhalidwe kuphwanya ndondomeko kumakhala ndi kukula kwakukulu kwa tinthu ndipo n'zovuta kugwiritsa ntchito mfundo yopulumutsira mphamvu yowonjezera kuphwanya ndi kupukuta pang'ono.Zomwe zimapangidwira ndi: kugwiritsa ntchito mphamvu zambiri, njira yayitali.Ambiri, kuphwanya ntchito kumafuna kugwiritsa ntchito zidutswa ziwiri kapena zingapo za wosweka kupeza abwino mankhwala kukula, izi zidzachititsa kuwonjezeka chiwerengero cha zidutswa zida kuphwanya chomera m'dera kuwonjezeka, pafupifupi kuonjezera ndalama likulu.Choncho, kupanga mapangidwe pogwiritsa ntchito zipangizo zazikulu, zophwanyidwa kwambiri ndizo chitukuko cha kuphwanya.

Pochita migodi, chinyezi chazinthuzo chimakhudza kwambiri zida zopangira mchere, kuthamanga kwachangu, kuphwanya mtundu, kuchuluka kwamadzi kumatha kupanga zida zina zotsekereza, kutsekeka kwa sieve mesh, kukhudza mtundu wazinthu, komanso kupanga kupanga. mzere Lekani kugwira ntchito, kubweretsa kutayika kwakukulu ku ntchito yopanga.Zida migodi mu ndondomeko mchere processing, zipangizo mgodi kwa mankhwala madzi ndi mbali yofunika kwambiri ya ndondomeko, zida migodi kwa kuchepa madzi m'thupi la mchere zambiri ndi makina yokoka, kuthamanga, mphamvu centrifugal ndi kupanga madzi m'madzi kapena kuyanika zipangizo. kupanga madzi evaporation , Kukwaniritsa cholinga madzi m'thupi.Zifukwa za kuchepa kwa mchere wa mchere pazifukwa zina ndi izi:

1.Kuchokera pamalingaliro azitsulo, kuyika madzi m'thupi pa smelting kumafunikanso kwambiri, kuwonjezereka kwa chinyezi kumangowonjezera mphamvu ya smelting, ng'anjo yazitsulo komanso kumachepetsanso coefficient yogwiritsira ntchito.Kuonjezera apo, kuchotseratu madzi opangira mchere kumafunikanso pofuna kupititsa patsogolo chitetezo cha chilengedwe kapena kuchepetsa kumwa madzi abwino m'madera omwe madzi akusowa.

2.M'dera lozizira, kusungirako ndi kuthamangitsidwa kwazinthu zomwe zimakhala ndi madzi ambiri zidzaundana ndipo zimakhala zovuta kwambiri kuti ziyendetsedwe.

3.Kuchokera ku kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake kake.

4.Osamangoganizira kutaya madzi m'thupi, monganso pazitsulo.Michira nthawi zambiri imakhala ndi chinyezi chopitilira 70% ndipo nthawi zambiri imathiridwa madzi isanalowe mu dziwe la tailings.
