Copper is one of the earliest human found and the metal used, purple, specific gravity 8.89, melting point 1083.4 ℃. Copper and its alloys due to the good electrical conductivity and thermal conductivity, high corrosion resistance, easy processing, good tensile strength and fatigue strength have been widely used, after the steel material and aluminum metal consumption, the national economy and defense become Basic materials and strategic materials that are indispensable in engineering and even high-tech fields. It has a wide range of uses in the electrical industry, machinery industry, chemical industry, and defense industry.
Copper is a typical sulphur-rich element. It mainly forms sulfides in nature. It forms oxides under strong oxidizing conditions and forms natural copper under reducing conditions. At present, more than 250 kinds of copper minerals and copper-containing minerals have been found on the earth's crust, mainly sulfides and their similar compounds and copper oxides, natural copper and copper sulfates, carbonates, silicates. Classes and other minerals. Among them, there are 16 kinds of industrial mineral raw materials that can be adapted to the current conditions of metallurgy. The natural elements: natural copper (containing nearly 100% copper); copper sulfide: chalcopyrite (including copper 34.6%, brackets refer to copper content, the same below), copper ore (63.3%), Hui Copper ore (79.9%), copper blue (66.5%), chalcopyrite (23.4%), beryllium copper (46.7%), arsenic antimony ore (52.7%), Sulfur-arsenic copper ore (48.4%); copper oxides: cuprite (88.8%), black copper (79.9%); copper sulfate, carbonate and silicate minerals: Malachite (57.5%), azurite (55.3%), chrysocolla (36.2%), water cholesteric (56.2%), chlorite (59.5%).
At present, the raw materials for copper smelting in China are mainly chalcopyrite, chalcopyrite, porphyrite, malachite and so on. According to the technical conditions of the metallurgy, the copper ore is divided into three natural types by the ratio of copper oxide and copper sulfide. That is, sulfide ore, containing less than 10% copper oxide; oxidized ore, containing more than 30% copper oxide; mixed ore, containing 10% to 30% of copper oxide.
China's copper mineral raw materials have the following characteristics:
1) Copper mineral raw materials suitable for smelting and production, occurring in various deposit types. Among them, the types of deposits with important mining value: magmatic copper- nickel sulfide deposit, porphyry copper deposit, skarn copper and polymetallic deposit, hydrothermal vein copper deposit, volcanic-deposited massive sulfide Type copper deposits, sedimentary layered deposits, and the like.
2) complex ore texture and structure, unevenness disseminated grain size, non-uniform multi disseminated ore particle, even many mineral compositions, fabric disseminated fine, complicated, more difficult mineral stone.
3) The ore has various chemical components, and it has many beneficial and harmful components associated with it. The process conditions of the metallurgy are complicated. At present, most of the mines developed are comprehensive copper deposits, with a variety of beneficial and harmful elements. Through comprehensive mining, comprehensive utilization, change harm to benefit, turn waste into treasure.

Commercial treadmills are mainly used in professional places with high usage such as gyms, clubs, and star rated hotels, with running belts generally between 45-65. Unlike home treadmills, commercial treadmills use an AC motor+frequency converter drive method, which can run for longer periods of time without causing the motor to burn out.

Is it worth buying a commercial gym treadmill?
Spending more upfront on commercial treadmills offers several benefits: Withstands high traffic and hours of use without breaking down. Advanced features better suit the gym/training environment. Covered by warranty when used properly.
What's the difference between a commercial treadmill and a regular treadmill?
Commercial electric treadmills are designed for heavy usage and are built with high-grade materials, making them more durable than home running machines. On the other hand, home treadmills are suitable for individuals who have limited time to exercise or prefer to workout in the comfort of their own homes
