“…Pressure filtration, in general, is preferred over vacuum filtration when the particle size is small, because of the high specific cake resistance, α av , and limited differential pressure achieved in vacuum filtration (Townsend, 2003).…”

Recovery of valuable metals from argon oxygen decarburization (AOD) dusts by leaching, filtration and solvent extraction

For each ton of steel produced from a typical steelmaking plant, up to several tens of kilograms of dust, containing significant amounts of valuable and/or environmentally harmful metals, are also produced. A hydrometallurgical route for the recovery of these metals from argon oxygen decarburization (AOD) dusts, with selective leaching, filtration and solvent extraction was studied experimentally. Batch leaching of dusts with concentrated H 2 SO 4 was found to be difficult to optimize for yields for the target metals (Zn and Mo), while keeping Fe in the solid phase. Zn and Mo could be recovered with comparable yields, while keeping Fe totally undissolved, by controlled leaching at pH above 3. Water was successfully used to leach Mo with 45% yield, while Ca, K, Cr, Mg, Pb, and Mn were leached as impurities. It was found that solid/liquid separation of the undissolved solids by pressure filtration was challenging and it was further observed that the properties of the initial dusts have a strong influence on this process step. D2EHPA was found to provide good extraction selectivity for Zn from acidic leaching solutions, except over Fe. A pure Mo/Cr mixture was extracted with hydroxyoxime LIX-84I, trioctylamine TOA and quaternary ammonium salt Aliquat 336. The best Mo/Cr selectivity was achieved with Aliquat 336.

“…Sıcaklığın 250˚C'ye kadar çıkarılabilmesi de filtrasyon verimi artırılabilmektedir (Andritz, 2020). Ayrıca plaka paketinin açıldığı, pompa ve yardımcı ekipmanların başlatıldığı ve valf çalışmasının yanı sıra kek boşaltımının otomatik olarak kontrol edildiği otomasyon sistemiyle çalıştırılan filtrelerin kullanımı da yaygınlaşmaktadır (Townsend, 2003).…”

Üçte ikisi sularla çevrili olan Dünya'nın su rezervlerinin %3'ünden daha az miktarını tatlı su kaynaklarının oluşturduğu bilinmektedir. Tatlı su kaynakların her geçen gün azalması, su kullanan endüstrileri, oluşturdukları atıksulardan elde edilen temiz suyu tekrar kullanarak faaliyetlerini sürdürmeye yöneltmektedir. Ülkemizdeki en büyük sanayi kollarından birisi olan madencilik sektörünün de hemen hemen her aşamasında su kullanılmaktadır. Çoğunlukla katı mineral taneleri ve sudan oluşan atıksuyun tesislerde tekrar kullanılabilmesi için içermiş olduğu katı mineral tanelerinden hızlı ve etkin bir şekilde kısmen/tamamen arındırılması gerekmektedir. Gerçekleştirilen katı/sıvı ayrımı ile sağlanan temiz suyun tesise tekrar beslenebilmesi ile madencilik faaliyetlerinin sekteye uğramadan devam etmesi sağlanmaktadır. Ayrıca; çeşitli yöntemler uygulanarak atıksudan temiz su kazanımı ile gerek tesisler için gerekli ilave su ihtiyacı azalmakta, gerekse doğada atıksu kaynaklı muhtemel kirliliğin önüne geçilebilmektedir. Bu bağlamda bu çalışma kapsamında; madencilik faaliyetlerinde yaygın olarak kullanılan atık su yönetimi ve katı/sıvı ayırma yöntemlerinin daha iyi anlaşılmasına katkı sağlanması amaçlanmıştır.

Strong competition in the process industries is forcing the optimization of process operation at each production level, including the operation of process equipment. Overall optimization of process equipment requires an efficient control strategy based on process models and a fault diagnosis system in order to prevent equipment malfunctions. In this paper an integrated operatorsupport system for a pressure filter is presented. The system structure is modular and consists of classification, modelling, optimization, fault diagnostic, and remote support modules. Finally the test results from a pilot plant and an industrial environment are presented and discussed. r
