pfd of copper smelting process
Flash smelting of copper requires 40 oxygen and 473K of hot air smelting the output of 65 copper matte can be implemented by thermal smelting. Selfheat smelting can not only reduce the energy consumption of smelting process but also reduce the flue gas volume thus reducing possible environmental pollution.
Flash Smelting an overview ScienceDirect Topics
The advantages of flash smelting over roasting/electric furnace melting are that flash smelting (1) requires much less energy than electric smelting and (2) avoids the electric furnace s emission of weak SO 2 gas 31 . It is also a high production rate process perfectly matched to the 50100μm particles in froth flotation concentrates.

SMELTING
The term smelting refers to the bulk production of the major metal bearing liquid phase as one of the process steps during the pyrometallurgical production of Metals. The liquid phase produced may be either a liquid metal sulfide ( matte) as in the production of Copper and Nickel or a metallic phase as in the production of Iron and Steel Lead

Lead Smelting an overview ScienceDirect Topics
Smelting of Lead. The conventional process for smelting lead involves roasting a mixture of lead sulfide concentrate and flux on a sinter machine followed by blast furnace smelting. Environmental and energy considerations have prompted studies of a more direct route a socalled "direct" smelting process.

What is Process Flow Diagram (PFD) Purpose Symbols Examples
Process Flow Diagrams or PFDs are developed using a series of symbols and notations to convey information for a process. The concept of PFD or process flow diagram was first introduced to ASME by Frank Gilbreth Sr. in the year 1921. Purpose of PFD or Process Flow Diagram. The purpose of the process flow diagram is to define the design of the
