The gold selection process is based on the ore selectivity test. Make necessary modifications during design and further improve and improve in production practice. It is decided that the production process is mainly in terms of ore properties and requirements for product form. The ore properties mainly include: gold grade, gold inlay size and occurrence form, type and grade of valuable components, surrounding rock properties and ore mud, mineral species and physical and chemical properties. The product form mainly refers to whether the gold in the product is in the form of a combination of gold (or pure gold) or gold concentrate. In general, it is best to produce finished or semi-finished gold near or in situ. Because this can reduce transportation costs and reduce the loss of gold during transportation. Shandong Province has made statistics on production in 1982. Every year, gold concentrates are transported from Yantai to Shenyang. The freight and road consumption are only two, and the annual loss is more than 3.3 million yuan. The near-input production of finished gold can also speed up the capital turnover of enterprises and is conducive to mine management. When the ore is more complicated, especially the difficult to choose polymetallic ore, if you want to obtain more technical indicators, the process will be more complicated. Therefore, when selecting a process, we must consider not only the technological advancement, but also the feasibility of production and economic rationality. Sandwich Panel Production Line is a good choice with Economy investment, flexible size panel, high quality. Machine is to make the sandwich panel with the color steel sheet or galvanized sheet and the core of polyurethane discontinuously. The multi-layered laminator is consisted of the press and the rail stands. Two worktables move into the press and the other two stay on rail stands. Initially, put the top and the bottom sheets inside of mould frames and then seal, after that, feed the worktables into the press. When worktables inside the press moves out orderly, the other two feed in at the same time. Upon the finish of feeding, the press will close and slant at a angle, waiting for injecting PU raw materials from the PU mixing head into different panels. Meanwhile materials start foaming and curing. At this time, mould frames on worktables moved out for taking out the finished products, then to be ready for next production cycle. The main laminator 2+2 produces PU sandwich panel with fixed length such as 6m, 9m, 12m, adjustable width less than 1.2m, different thickness from 50mm to 250mm by the closed molding frame.

For small and medium-sized gold-mining factories, we must adhere to the principle of “multiple, fast, good and provincial†in the process selection. In the spirit of adapting to local conditions, combining soil and ocean, and being easy to choose, we should try our best to make less investment, get on the fast, and get out of gold early. More gold.
