Flotation containing two or more useful components of a multi-metal ore, we must first solve the problem of the recovery order in a variety of useful minerals. If the first mineral is first floated to suppress the remaining minerals, and then the other mineral that is inhibited is activated and floated, the process of recovering useful minerals in turn is called a preferential flotation process. For example, copper zinc ore flotation process is shown in FIG. This process is based on the difference in the floatability of the mineral, which is preferentially floated and then floated. If in the above case, two or more useful minerals of the ore are first floated together to obtain a mixed concentrate, and then the mixed concentrate is sorted to obtain qualified concentrates of different useful minerals. It is called a full flotation process or a hybrid flotation process. For example, the principle of mixed flotation of copper-zinc ore is shown in Figure 2. This process is to float all the copper and zinc to obtain mixed concentrate and waste tailings. The mixed concentrate is reground or de- pulverized, and then the copper is preferentially floated to obtain a copper concentrate, which is a zinc concentrate. When more than three useful minerals are recovered, a partial mixing flotation process can also be used, as shown in Figure 3. It differs from the full flotation process in that a portion of the useful mineral to be floated is first mixed out.
Exhaust
Muffler
Mufflers
are installed within the exhaust system of
most internal combustion engines. With high performance
SS304 stainless steel universal mufflers can give you added power and a racing
sound over stock mufflers. With high-temperature fiber glass wool and stainless
mesh wrapped around the perforated hole.
The
muffler is engineered as an acoustic soundproofing device
designed to reduce the loudness of the sound pressure created
by the engine by way of acoustic
quieting.
The
majority of the sound pressure produced by the engine is emanated out of the
vehicle via the same piping used by the silent exhaust gases. The emitted noise
is abated by a series of passages and chambers lined with roving fiberglass insulation
and/or resonating chambers harmonically tuned to cause destructive interference, wherein opposite
sound waves cancel each other out.

ends can be added for clamping installations, to connect muffler and Catalytic
converter..

The floatable process is also called the hybrid flotation process. As shown in Figure 4. It is to divide the useful minerals to be floated into two parts, easy to float and difficult to float according to the floatability. They are separately floated in the order of easy and difficult, and then separated. It is applicable to the same minerals including complex polymetallic ores that are both easy to float and difficult to float.
