Lingaliro Latsopano Padziko Lonse Lapansi Pazoyang'anira

Masoka achilengedwe a ma tailing siachilendo m'makampani ogulitsa migodi. Komabe, pambuyo pa tsoka la damu la Brumadinho ku Brazil ku 2019 kumene 12 zinyalala zachitsulo miliyoni miliyoni zidatulutsidwa mwangozi, kupha osachepera 134 anthu ndikuwononga chilengedwe, Kuwunika kwa Global Tailings kwatsogola pamachitidwe apadziko lonse lapansi pakuwongolera zoyeserera. Malangizowa akunena kuti kulephera kwa malo osavomerezeka sikuvomerezeka, ndipo kuti ogwira ntchito sayenera kulolera konse kuvulala kwa anthu kapena kufa ndipo ayenera kuyesetsa kuti asawononge chilengedwe.

Madera omwe akukambidwa pamwambowu akuphatikizanso:

• Malo Amutu 1:- Anthu ndi madera omwe akhudzidwa ndi projekiti.
• Malo Amutu 2:- Zachikhalidwe, zachilengedwe, ndi nkhani zachuma.
• Malo Amutu 3:- Kupanga, zomangamanga, opareshoni, kukonza, kuyang'anira, ndi kutseka ma tailing.
• Malo Amutu 4:- Kuwongolera ndi kuwongolera malo.
• Malo Amutu 5:- Kukonzekera mwadzidzidzi, yankho, ndikuchira kwanthawi yayitali.
• Malo Amutu 6:- Kuwululidwa pagulu ndikupeza chidziwitso.

Kuphatikiza pamitu isanu ndi umodzi, alipo 15 mfundo zomwe migodi iyenera kutsatira, komanso 77 zofunikira kuwunika.

Mutha kutsitsa PDF yonse ya Global Industry Standard pa Tailings Management Pano.

cha ku Switzerland Zida & Technology ikukhulupirira kuti pali chinthu chimodzi chomwe chikuyenera kuwonjezedwa pamndandanda wambiri. Izi ndikuti muchepetse kuchuluka kwa ma tailings opangidwa koyambirira. Ndi yathu tribo-electrostatic kulekana ndondomeko, titha kutenga zinthu zambiri zaku minda zomwe nthawi zambiri zimathera mumtsinje wa zinyalala. Izi sizimangopereka mwayi wopeza phindu lalikulu kuchokera kuzinthu zomwe zidayimbidwa, zitha kuchepetsa kwambiri kuchuluka kwa zinyalala zopangidwa munjira zosiyanasiyana monga kutulutsa alumina kuchokera ku bauxite.

Njira yatsopano yotchedwa Bayer imagwiritsa ntchito zida zopangira, kutentha kwambiri, ndi kuthamanga kwambiri kuti alumina osiyana ndi zipangizo ozungulira bauxite. Mtsinje wotsatirawo umabweretsa slurry wotchedwa matope ofiira, zomwe ziyenera kusungidwa m'madziwe mpaka poizoni atatha.

wathu lamba olekanitsa Ndi njira yamagetsi yogwiritsira ntchito njira yopatukana youma yomwe ingagwiritsidwe ntchito njira ya Bayer isanatulutse alumina ambiri koyambirira. Izi zimapangitsa kuti zinthu zachilengedwe zothandiza zipezenso, kufunika kocheperako kwa zida zakupha ndi mphamvu zomwe zimagwiritsidwa ntchito ndi Bayer, kuchepetsa kufunika kwa madzi abwino, ndi kuchepa kwakukulu kwa kufunika kosunga mayiwe.

Momwe miyezo yapadziko lonse lapansi ikupitilizabe kusintha ndipo makampani akumigodi akufunafuna magwiridwe antchito abwino osanyalanyaza malangizo oyenera kuteteza anthu komanso chilengedwe, cha ku Switzerland Zida & Technology idzakhala yokonzeka kupereka mayankho abwinobwino pachuma.
