Hazardous solid waste from metallurgical industries.
Types of land disposed residuals from selected metal smelting and refining industries are described, as are the origin and disposition of land disposed residuals from the primary copper industry as an example. Quantities of land-disposed or stored residuals, including slags, sludges, and dusts, are given per unit of metal production for most primary and secondary metal smelting and refining ind...
متن کاملRF Thermal Plasma Synthesis of Ferrite Nanopowders from Metallurgical Wastes
RF thermal plasma synthesis of zinc-ferrite nanopowders has been studied from metallurgical wastes of high iron oxide and zinc oxide and/or hydroxide content. XRD measurements of the products revealed that an extensive spinel formation took place on RF plasma treatment. However, instead of expectable ZnFe2O4, formation of zinc ferrous ferrites (Zn0,7Fe2,3O4 and Zn0,4Fe2,6O4) was concluded from ...
متن کاملa study on the design of bio-ethanol process from date wastes of sistan and baluchistan province
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...
Risk identification, assessment and management in the mining and metallurgical industries
They suggest that increased importance be attached to the pre-investment phase as a project will succeed, or fail, on the marketing, technical, financial and economic findings and their interpretation, particularly at this stage. The pre-investment phase comprises; ➤ Identification of investment opportunity ➤ Analysis of project alternatives ➤ Preliminary project selection ➤ Pre-feasibility and...
متن کاملBiotechnology in the Mining and Metallurgical Industries: Cost Savings through Selective Precipitation of Metal Sulfides
The PAQUES Bio Systems’ core technology, marketed under the name THIOPAQ, consists of various high-rate biological processes for metal-sulfur-water systems, complemented with common solid/liquid and gas separation steps. Sulfur species are converted to sulfide, which is a valuable component as it can be used for metals reduction and precipitation. Selective recovery of valuable metals can be em...
