The paper describes the application practice and successful operating experience of the Isa smelting technology in Yunnan Copper Corporation and presents in details the improvements of the Isa furnace related to treatment rate,operating rate,refractory material life,dust yield,and service life of lance,etc.

The technological pro-cess is possessed of advantages of low dust yield,high production capacity of fluidized-bed roasting,etc.

The bag filter of the 5t electric furnace at Jigang Mechanical Equipment Manufacturing Factory has never operated smoothly before for the body deformation, designing default and cumulative error of the filter, which cause various of malfunctions including rotating arm breaking,bags hardshelled and low dust arrestment rate etc.

new technology can successfully collect the indium from the flue dust from lead dross reverberatory.

The collector can effectively get rid of the flue dust from manual boiler,and realize internal circulation of dust,collection water and eliminate the secondary pollution problem.

The necessity of on-line monitoring of flue gas amount and components of flue dust is put forward.

The pollution and danger of the smoke and dust from the coke oven to the man and environment were outlined.

Two trapping methods are discussed in accordance with the situation to disorderly discharge smoke and dust on electric furnace slag field and the features of the smoke and dust.

This paper introduces the reasons and the harm of the coming into being of the boiler s smoke and dust,flue gas.
