Golden sand mining waste water purification treatment for complex issues, whether it is gold mining ship or hydraulic placer mining, mineral processing and waste water generated are different from other sewage. This is mainly determined by the nature of the ore. Because the sand mining operation consumes a large amount of water, the amount of sewage is large, and it contains a large amount of mineral particles, clay and mechanical impurities suspended in a high-fine particle dispersion. When sand minerals with a high clay content are mined, there is a large amount of suspended solids, and the sedimentation rate of these suspended solids is very slow. When using closed-circuit circulation water supply, in order to accelerate the clarification and cleaning of the mineral water, the sewage also contains various additives.
Sand gold mine sewage treatment usually uses the following methods:
1. A sedimentation tank with dykes is built downstream of the working area of ​​the gold mining vessel for clarification of the sewage, and the treated water can be used for closed circulation;
2. When the gold mining vessel operates in closed waters, most of the river water flows out through the drainage ditch;
3. In order to reduce the degree of pollution, the suspended matter may be flocculated and precipitated by chemical method or electrolysis method.
Sheet Metal Fabrication Service
Sheet metal processing of sheet metal fabrication service is an important process for forming sheet metal products. Sheet metal processing includes traditional cutting, punching, bending, and forming methods and process parameters, as well as various cold stamping die structures and process parameters, various equipment working principles and operating methods, and new stamping technology and new technology. Part metal sheet processing is called sheet metal processing. The materials generally used in sheet metal processing are cold-rolled sheet (SPCC), hot-rolled sheet (SHCC), galvanized sheet (SECC, SGCC), copper (CU) brass, red copper, beryllium copper, aluminum sheet (6061, 5052, 1010, 1060, 6063, duralumin, etc.), stainless steel (mirror surface, brushed surface, matte surface), depending on the function of the product, the selection of materials is different, generally, it is necessary to consider the use and cost of the product.
Sheet metal processing has the following characteristics:
The beam is easy to control: it is easy to combine with precision machinery, precision measurement technology, electronic computer, etc. to achieve high precision and high automation.
High power density: When the workpiece absorbs the rapidly rising temperature during the sheet metal process, even materials with high melting points, high hardness, and high brittleness (such as ceramics, diamonds, etc.), will melt or evaporate.
Wide range of applications: the divergence angle of the sheet metal machining beam can be less than 1 milliarc, the diameter of the spot can be as small as microns, and the action time can be as short as nanoseconds and picoseconds. At the same time, the continuous output power of high-power plate processing can reach kilowatts to ten kilowatts.
Convenient and flexible: Robots can process sheet metal in harsh environments or places that are inaccessible to others.
