Exhaust
system
An exhaust
system is usually piping used to guide reaction exhaust gases away
from a controlled combustion inside an engine.
The Whole Exhaust System conveys burnt gases from the engine and includes one
or more exhaust pipes. Depending on the overall system design, the exhaust
gas may flow through one or more of:
· Exhaust head and exhaust manifold
· A turbo to
increase engine power.
· A three
way Catalytic Converter to reduce air pollution.
· A muffler / silencer
to reduce noise.
· A exhaust
tip to look better

Copper tailings recovery sericite example (Jiangxi Copper Company)
Jiangxi Copper Industry Company under the mountain of silver lead zinc mine tailings can be produced every year about 500 000 t, second only to the content of the tailings sericite quartz, which lead-zinc tailings, sulfur, copper tailings, tailings pond in The content is 33%, 34% and 29%, respectively, and the sericite reserves are 3.6 million tons. The plant adopts flotation method to recover sericite from lead-zinc tailings and copper-sulfur tailings. The principle process is shown in Figure 1. The result is that the recovery rate of sericite from copper-sulfur tailings is 63.79%.
The sericite grades of concentrate I and concentrate II are 96.70% and 64.50%, respectively; the recovery rate of sericite in lead-zinc tailings is 58.12, and the sericite grades of concentrate I and concentrate II are 96.2% and 62.5%, respectively. .
