Abstract

   Since the
comminution process is the most energy consuming part of the whole mining
operation, it is well known that energy optimization can be provided with the
aid of modelling and simulation studies. Within the scope of the study, the
simulation studies performed for wet grinding circuit processing chalcopyrite,
sphalerite and pyrite minerals are presented. Initially, sampling campaign was
arranged around the circuit that consisted of two ball mills and a hydrocyclone
cluster system. Then the size distributions together with the chemical assays
were determined. Afterwards, mass balancing around the circuit was performed
and the model structures of the equipment were developed. Model of the whole
circuit was used to simulate different operating conditions. Initially, solid
content of the primary ball mill was adjusted and apex/vortex geometries of the
hydrocyclone were redesigned. As a consequence of the simulations, the dry
tonnage of the feed to the circuit was increased from 172.5 t/h to 190 t/h and
then 195 t/h that corresponds to increase by 10% and 13%. Finally, the second
option was chosen for the plant and the real production rate was increased to
195 t/h.

Abstract

   Cevher hazırlama
süreci içerisinde enerjinin en yoğun harcandığı birim işlem kırma ve öğütme
olup modelleme ve simülasyon çalışmaları ile enerji optimizasyonunun
sağlanabileceği bilinmektedir. Bu çalışma kapsamında, kalkopirit, sfalerit ve
pirit minerallerinin öğütüldüğü yaş çalışan bir öğütme devresinde
gerçekleştirilen simülasyon çalışmalarının sonuçları sunulmaktadır. Çalışmada
ilk olarak 2 adet bilyalı değirmen ve siklon bataryası bulunan tesisten
numuneler alınmış ve boyut dağılımı, kimyasal analiz gibi ölçümler yapılmıştır.
Sonrasında devreye ait kütle denkliği kurulmuş ve ekipmanlara ait model
yapıları geliştirilmiştir. Model yapılarının geliştirilmesinin ardından farklı
simülasyon senaryoları üzerinde durulmuştur. Sırasıyla, birincil bilyalı değirmenin
çalışma %katı değeri ve hidrosiklona ait apex ve vortex parametreleri
değiştirilmiştir. Tesiste yapılan değişiklikler neticesinde, besleme kuru
tonajı 172,5 t/sa değerinden 190 t/sa ve 195 t/sa değerine çıkartılmış olup
artış oranı sırasıyla %10 ve %13 olarak hesaplanmıştır. Bilgisayar ortamında
tamamlanan hesaplamaların ardından işletme tarafından ikinci alternatif
seçilmiş ve fiili olarak tonaj değeri 195 t/sa değerine çıkartılmıştır.
