The second chapter located the status from the Chinese zinc smelting industry in the whole world, the zinc market supply and demand condition, the domestic zinc consumption pattern, the zinc market competition pattern and the zinc product market competition characteristic five aspects carries on theanalysis to the zinc product market, also the stress point lay in the domestic zinc product market analysis.
The technological feasibilitics of sulfur dioxide removal from waste geses of smelting industry by suspended aqucous solution of pyrolusite arc studied. The ways that restrain production of MnS_2O_6 that is by-product are posed.
According to the characteristics of high-temperature gas of the copper smelting industry,the existing structural defect of large industrial blower rotor which is now used for high-temperature gas emissions in domestic copper smelting industry is pointed and the effective improvement have finished.
The over competition of zinc smelting industry in Chinese mainland and unre-strained expansion of zinc production capacity result in the increase of economic losses of do-mestic enterprises,the decrease of the efficiency of resources collocation,and the deterioration of environment.
Coreless working-frequency induction furnace is the important equipment in smelting industry. The quality of lining, which is the key section of the induction furnace, will affect the service life of furnace and smelting costs directly.
These drinking vessels not only prove the ancient history of China alcoholic drink culture,also reflect the broad social life contents,including primitive agriculture,smelting industry,religious beliefs,esthetics,language and word and so on.
The emission coefficient of SO2 from non-ferrous metal smelting industry, dust from cement producing industry, flue dust from iron and steel industry and the calculation methods are introduced in this paper.
The use of arsenic trioxide in water-borne preservative systems such as chromated copper arsenate provides a major market for arsenic-trioxide production from the nonferrous roasting and smelting industry.
Continuous converting of copper matte based on calcium ferrite slag has many attractions for the copper smelting industry.
A wide range of slag compositions of interest to the nonferrous smelting industry was reduced and oxidized using mixtures of CO, CO2, and Ar.
Results of an experimental study of thermosilicate heat-insulating materials for the aluminum-smelting industry based on microsilica and wollastonite (an alternative to anthophyllite asbestos) are reported.
Sulphur emissions from the Sudbury, Ontario, metal smelting industry have affected thousands of lakes in Ontario, Canada.
This paper systematically summarizes the development of zinc smelting industry in the world. It concentrates on accelerating tech- nical innovation and exploiting new refining methods so as to bring up expe- riences available for our zinc smelting industry.
The technological feasibilitics of sulfur dioxide removal from waste geses of smelting industry by suspended aqucous solution of pyrolusite arc studied.The ways that restrain production of MnS_2O_6 that is by-product are posed.
In order to control total air emission it is necessary to determine the quantity of air pollutant emission in the experimental unit of permit system for air pollution in China.The emission coefficient can be used to calculate the quantity of emission from different air pollution source. The emission coefficient of SO2 from non-ferrous metal smelting industry, dust from cement producing industry, flue dust from iron and steel industry and the calculation methods are introduced in this paper.
