Foam and bubble during cyanide leaching

[kodel80]

halo semuanya saya dari indonesia..saya mau tanya tentang munculnya busa dan gelembung pada proses sianida. bahan low sulfide digiling sehingga lolos 150 mesh. kemudian saya masukkan kapur sebanyak 5kg dan naoh sebanyak 1kg. setelah tercampur muncul gelembung dan saya biarkan selama 12 jam busa dan gelembung bertambah. setelah 12 jam saya masukkan h2o2 sebanyak kurang lebih 200ml dan busa dan gelembung bertambah. kemudian saya masukkan nacn sebanyak 600 gram dan sedikit pbno3. saya biarkan selama 4 jam kemudian saya masukkan karbon aktif. setelah 24 jam busa dan gelembung tidak berkurang tetapi bertambah. menurut pengalaman saya setelah memasukkan karbon biasanya busa berkurang. tetapi pada proses ini busa tidak berkurang sama sekali. pertanyaan saya apakah busa dan gelembung tersebut mengandung logam atau hanya reaksi. terima kasih

first video after kaput and naoh are added. second video after h2o2 is added and cyanide is given. third video after 24 hours of activated carbon is added

video pertama setelah kaput dan naoh ditambahkan. video kedua setelah h2o2 ditambahkan dan diberikan sianida. video ketiga setelah 24 jam karbon aktif ditambahkan

pengukuran terakhir
Ph 11.66
Do 9,1 mg/l

hello everyone i am from indonesia..i want to ask about the appearance of foam and bubbles in the cyanide process. low sulfide material is ground so that it passes 150 mesh. then i put in 5kg of lime and 1kg of naoh. after mixing bubbles appear and i leave it for 12 hours the foam and bubbles increase. after 12 hours i put in h2o2 as much as approximately 200ml and the foam and bubbles increase. then i put in 600 grams of nacn and a little pbno3. i leave it for 4 hours then i put in activated carbon. after 24 hours the foam and bubbles do not decrease but increase. in my experience after putting in carbon usually the foam decreases. but in this process the foam does not decrease at all. my question is do the foam and bubbles contain metal or are they just reactions. thank you

What has changed in your process?
New material or new chemicals?
