Value addition of copper sulphide from nickel refining: Process modelling and simulation
نویسندگان
چکیده
The aim of the study was to develop a process option for value addition leach residue from hydrometallurgical nickel refining. in question is copper-rich (58 %) with sulphur (23 %), (3 and iron (2 as other main constituents. prevailing phases are covellite antlerite already marketable product such. current suggests flow sheet moderate temperature autogenous pressure leach, selenium removal copper electrowinning. Precious platinum group metals will enrich solid phase. Further solution purification be considered if London Metal Exchange grade desired. modelled steady-state proposal made integration into bleed requirement developed circuit 51 % spent electrolyte, which may treated utilised preceding In addition, sensitivity analysis conducted obtain data adapting suit refining navigate way forward development project. simulation showed that circuit, case leaching, would produce more than 300 kg acid per tonne feed, need bled out.

اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
From Process Modelling to Enactment and Simulation
The usefulness of simulation and enactment in business process modelling is explored by means of studying a simple process. Two roles with interactions (contacts), rework and choices collaborate in the production of a document (loan, policies, etc.) From its Role Activity Diagram (RADs), we construct models for Discrete Event (DE) and System Dynamics (SD) simulation and Process Enactment (PE) i...

in this work, we developed a method which combined the processes of acid-leaching, ammonium jarosite precipitating and electro-depositing to recover copper and nickel from electroplating sludge. residual sludge from an electroplating plant located in qingdao was used for acid-leaching, and more than 95% of copper, nickel, zinc, chromium and iron were extracted from the sludge. after acid-leachi...

Removal of B from Si by Hf addition during Al–Si solvent refining process
A small amount of Hf was employed as a new additive to improve B removal in the electromagnetic solidification refinement of Si with an Al-Si melt, because Hf has a very strong affinity for B. The segregation ratio of Hf between the solid Si and Al-Si melt was estimated to range from 4.9 × 10-6 to 8.8 × 10-7 for Al concentrations of 0 to 64 at.%, respectively. The activity coefficient of Hf in ...
