Selection basis for gold ore production process

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.
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.

Limiter & Limit Switch

A limiter for a Tower Crane is a safety device that is installed to prevent the crane from operating beyond its maximum load capacity or from moving beyond its designated working area. It typically consists of sensors, control systems, and alarms to ensure safe operation.

The load limiter is designed to monitor the load being lifted by the crane and automatically stop the crane's movement if the load exceeds the specified limit. It helps prevent overloading, which can lead to structural failure or accidents.

The radius limiter is used to restrict the crane's movement within a specific working area. It ensures that the crane does not extend beyond its designated radius, preventing it from colliding with nearby structures or obstacles.

Both types of limiters are essential safety features in tower cranes to protect workers, equipment, and the surrounding environment. They help ensure that the tower crane operates within its safe working limits and minimize the risk of accidents or damage.
