Nickel mining rely mainly on open-pit mining in the past 80 years, there are open pit Jinchuan Nonferrous Metals Company and Jilin Nickel Industry Company wealthy Ridge open pit and large open pit mine, ore with an annual output capacity of 2 million t. By the mid-1980s, the Jinchuan No. 2 Mine was completed and put into operation, which caused the main nickel concentrate of nickel production in the country to come from underground mining. By the end of the 1980s, the open pit mines were successively mined and transferred to underground mining.

At present, nickel ore is all dependent on underground mining. Under the guidance of the planned economy before the 1980s, the mining method was relatively backward, and mining was mainly carried out by electricity and labor. In order to reduce capital investment, many mines have adopted the caving method, and the depletion rate and loss rate are more than 20%. Since the late 1960s, a series of process technologies have been carried out with the Jinchuan Nickel Mine as the first cement-filling mining method. Now this method has been applied to the majority of nickel mines. The mining methods for the main nickel mines in China are shown in the table below.
At present, 90% of the mining volume of China's nickel mines is cemented and filled, and the recovery rate can be controlled at about 95%. The ore grade is 20% to 30% higher than the caving method, which lays down the ore recovery rate and the concentrate grade. A good foundation.
Aluminum Die Casting has different names in different places, such as aluminum die casting parts, die-cast aluminum parts, Aluminum Casting parts,Cast aluminum, aluminum die casting parts and so on. Metal aluminum and aluminum alloy with good fluidity and plasticity, and aluminum die casting can make a variety of more complex shapes can also be made of high accuracy and finished, to a large extent reduce machining allowance and casting margin, not only saves electricity, aluminum materials, but also significant savings in labor costs; with excellent thermal conductivity of aluminum and aluminum alloy , the smaller the proportion and high workability; So aluminum die castings are widely used in automobile manufacturing, lamp parts, engine production, motorcycle manufacturing, oil production, transmission machinery, precision instruments, electrical construction, building and decorating and other industries.
Aluminum die casting parts also can be manufactured aluminum die-cast auto parts, aluminum die casting automotive engine fittings, aluminum die-casting Engine Cylinder, aluminum die-casting gasoline engine cylinder cylinder head, valve rocker of aluminum die casting, aluminum die-casting valve bearings, aluminum die-casting power accessories, aluminum die casting motor end caps, aluminum die casting housing, pump housing of aluminum die casting, aluminum die casting construction accessories, decorative accessories of aluminum die casting, aluminum die casting fence accessories, aluminum die-cast aluminum wheel, etc.
