“…All the representative combinations distribute uniformly in the research area and can greatly reflect the situation of the whole selected examined area. This method has proven to be a cost-effective optimization strategy that can obtain the optimal conditions of each parameter in a limited number of experimental trials [24][25][26][27]. Therefore, this paper discussed four main process conditions in the transesterification reaction (i.e.…”

Mineral depositions are basic sources for obtaining metal production. Increasing metal demand based on increasing world population and decreasing grade value of mineral deposition make the evaluation to mineral processing more important, so that all metal production stages must be economical. Because of this important requirement, many researchers and practitioners have focused to the optimization of all processes. The optimization of metal production processes provide some advantages such as reducing the influence of experimental errors, statistical analysis, determining important parameters and trivial parameters, and measuring interactions between parameters. Although there are many design methods, choosing the most appropriate method is of great importance in terms of the results to be achieved. In this chapter, presumed experimental data about hydrometallurgical copper extraction accompanied by three parameters were applied to two different design models to compare the results.

ÖzetBu çalışmada, Türkiye'de ikincil atıklardan üretim yapan bir firmadan tedarik edilen ve %23.1 Cu, %20.5 Sn ve %15.4 Pb temel kimyasal kompozisyonuna sahip anot çamurundan bakır geri kazanımı için çevreye duyarlı yeni bir çözücü olan 1-etil-3-metil-imidazolyum hidrojen sülfat (EmimHSO 4 ) iyonik sıvısı kullanımı araştırılmıştır. Yapılan deneysel çalışmalarda, bakır geri kazanımını etkileyen iyonik sıvı konsantrasyonu, sıcaklık, süre ve katı/sıvı oranı parametreleri incelenerek bakır için optimum geri kazanım koşulları Taguchi metodu ile belirlenmiştir. Varyans analizi yöntemi (ANOVA) kullanılarak optimum koşullar altında, bakır geri kazanımı için en etkili parametreler belirlenmiştir. Elde edilen sonuçlara göre bakır kazanımı için optimum koşullar; iyonik sıvı konsantrasyonu: %60, sıcaklık: 95 o C, süre: 2 saat ve katı/sıvı oranı: 1/20 olarak tespit edilmiştir. Bakır kazanımı için en etkili parametrelerin sırasıyla, reaksiyon süresi, sıcaklık, katı/sıvı oranı ve iyonik sıvı konsantrasyonu olduğu belirlenmiştir. The Effect of EmimHSO AbstractIn this present study, a new solvent called 1-ethyl-3-methyl-imidazolium hydrogen sulphate (EmimHSO 4 ) was used for recovery of copper from anode slime. Sample whose compounds are mainly of 23.1% Cu, 20.5 %Sn and 15.4% Pb was provided from a copper refining plant making production from secondary grade wastes in Turkey. The optimum metal recovery conditions for copper including ionic liquid concentration, temperature, time and solid/liquid ratio which affect the leaching efficiency were investigated in the experiments were detected by Taguchi method. Also, the most effective parameters under the optimum conditions for copper metal recovery were determined by analysis of variance method (ANOVA). According to the experimental results, optimum conditions for copper recovery were found as for ionic liquid concentration; 60%, for temperature; 95 o C, for time; 2 hours and for solid/liquid ratio; 1/20. The most effective parameters determined as leaching duration, temperature, pulp density (solid/liquid ratio) and ionic liquid concentration, respectively.
