Matatu Akajairwa Goridhe Ore Leaching Maitiro

Mu Leaching Process zvezvishandiso, zvichibva pamusiyano wekuyerera kwemidziyo yakavharwa uye leaching reagents, matatu leaching maitiro anogona kuzivikanwa.

1. Co-current Leaching

Mukubatana-ikozvino leaching, iyo leached zvinhu uye leaching reagents inoyerera munzira imwechete (Mufananidzo 1). Iyi nzira inogona kuburitsa leachate ine yakawandisa yemukati yezvinotangwa zvikamu uye inoda kuderera kudyiwa kweleaching reagents. Nekudaro, iyo leaching kumhanya inononoka. Nguva yakareba yeleaching inodiwa kuti uwane yakakwira leaching rate.

2. Muchinjikwa - ikozvino Leaching

Muchinjika-yazvino leaching, izvo zvakavharwa zvakaiswa zvakasiyana nezvikamu zvakati wandei zveakachena leaching reagents. Iyo leachate inowanikwa kubva kune yega yega leaching inoshanda inotumirwa zvakafanana kune inotevera kugadzirisa (Mufananidzo 2). Muchinjikwa - ikozvino leaching inoratidzira inokurumidza leaching kumhanya uye ipfupi leaching nguva, zvichikonzera yakakwira leaching rate. Zvakadaro, vhoriyamu yeleachate yakakura, ine huwandu hwepamusoro hwezvakasara reagents. Nekuda kweizvozvo, kudyiwa kwemareagents kwakakura, uye zvirimo zvezvinotarirwa zvikamu muleachate zvakaderera.

3. Counter - ikozvino Leaching

Mukupikisa - ikozvino leaching, iyo leached zvinhu uye leaching reagents zvinofamba zvakapesana. Kureva kuti, zvinhu zvakapera mushure mekuvhiyiwa kwakati wandei zvinosangana neakachena leachate, nepo zvekutanga zvakanyungudutswa zvinobata leachate (Mufananidzo 3). Counter - yazvino leaching inogona kuburitsa leachate ine yakakwira yemukati yezvinotangwa zvikamu uye kushandisa zvizere zvakasara reagents muleachate, nekudaro kuderedza kudyiwa kweleaching agents. Nekudaro, iyo yekumhanyisa kumhanya yakaderera pane iyo yekuyambuka - ikozvino leaching. Huwandu hukuru hwematanho ekuleaching anodiwa kuti uwane yakakwira leaching rate.

Percolation tank leaching inogona kutora co - yazvino, muchinjiko - yazvino, kana counter - yazvino leaching maitiro. Heap leaching uye in-situ leaching inowanzo shandisa iyo-yazvino cyclic leaching process. Kuenderera mberi kwakasimudzwa leaching kazhinji kunotora iyo co - current leaching process. Kana muchinjiko - wazvino kana counter - ikozvino leaching ichashandiswa, yakasimba - yemvura yekuparadzanisa mashandiro anofanirwa kuwedzerwa pakati pechikamu chimwe nechimwe. Batch - yakashandiswa yakasimudzwa leaching inowanzobatana - ikozvino leaching, asi muchinjiko - wazvino kana counter - ikozvino leaching inogona kuiswa zvakare. Nekudaro, kwakasimba - kuparadzaniswa kwemvura kunodiwa mushure mekushanda kwega kwega, zvichiita kuti kushanda kuome uye kusanyanya kushandiswa mukugadzira. Percolation leaching inogona zvakananga kuwana leachate yakajeka, ukuwo slurry kubva mukusimudzwa leaching inofanirwa kuomarara - kupatsanurwa kwemvura kuti iwane yakajeka leachate kana kunyungudutsa slurry ine chidimbu chidiki cheore kuti chizogadziriswa.
