Bunlar, b\u00fcy\u00fck tanecikli alt\u0131n\u0131n \u00e7\u0131kar\u0131lmas\u0131 i\u00e7in kullan\u0131lan y\u00f6ntemler olmakla birlikte, g\u00fcn\u00fcm\u00fczde bu b\u00fcy\u00fckl\u00fckte alt\u0131n tanecikleri bar\u0131nd\u0131ran madenlere pek rastlanm\u0131yor. Bu nedenle, en \u00e7ok kullan\u0131lan y\u00f6ntem siyan\u00fcr li\u00e7i. Bu y\u00f6ntemde, k\u0131rma-\u00f6\u011f\u00fctme, siyan\u00fcrleme, karbonla tutma, aktif karbondan s\u0131y\u0131rma, elektroliz ve at\u0131klar\u0131n ar\u0131t\u0131lmas\u0131 a\u015famalar\u0131 izleniyor. \u0130lk ad\u0131mda ocaktan \u00e7\u0131kar\u0131l\u0131p k\u0131r\u0131c\u0131da m\u0131c\u0131r boyutuna getirilen cevhere pH\u2019\u0131 10,5\u2019in \u00fcst\u00fcnde tutmak i\u00e7in kire\u00e7 ekleniyor. Bu, siyan\u00fcr\u00fcn d\u00fc\u015f\u00fck pH ortam\u0131nda hidrojen gaz\u0131na d\u00f6n\u00fc\u015f\u00fcp havaya kar\u0131\u015fma tehlikesini \u00f6nlemek i\u00e7in yap\u0131l\u0131yor. Daha sonra cevher, alt\u0131n\u0131n serbestle\u015fme tane boyutu olan 38 mikrona kadar \u00f6\u011f\u00fct\u00fcl\u00fcyor. \u00d6\u011f\u00fct\u00fclen k\u0131s\u0131m %45\u2019i kat\u0131, %55\u2019i s\u0131v\u0131 olacak \u015fekilde yo\u011funla\u015ft\u0131r\u0131l\u0131yor.

Karbon, \u00e7\u00f6z\u00fcnm\u00fc\u015f haldeki alt\u0131n ve g\u00fcm\u00fc\u015f\u00fc \u00e7amurun i\u00e7inden s\u0131y\u0131rmaya yar\u0131yor. Alt\u0131n ve g\u00fcm\u00fc\u015f, karbon y\u00fczeyine tutunuyor. Elekten ge\u00e7irilen \u00e7\u00f6zeltide, karbon taneci\u011fine tutunan alt\u0131n ve g\u00fcm\u00fc\u015f elekte kal\u0131rken geri kalan k\u0131s\u0131m at\u0131k tanklar\u0131na g\u00f6nderiliyor. Elekte kalan karbon, s\u0131y\u0131rma kolonunda asit, su ve siyan\u00fcrle y\u0131kan\u0131yor. Burada, karbona yap\u0131\u015fan alt\u0131n ve g\u00fcm\u00fc\u015f karbondan ayr\u0131l\u0131yor. Alt\u0131n ve g\u00fcm\u00fc\u015f i\u00e7eren s\u0131v\u0131, elektrolit h\u00fccrelerinden ge\u00e7iriliyor. Buradaki \u00e7inko g\u00f6zeneklere elektrik verildi\u011finde, y\u00fckl\u00fc alt\u0131n ve g\u00fcm\u00fc\u015f tanecikleri bu g\u00f6zeneklerde toplan\u0131yor.
