The technical and economic indicators of heap leaching are external manifestations reflecting the level of heap leaching technology and economic effects. What affects technical and economic indicators is the objective factor in the heap leaching process. Some of these factors also affect several technical and economic indicators. For example, the nature of the ore affects both the leaching rate and the recovery rate, as well as the consumption of reagents. It is also a key factor in determining the emissions of the three wastes. Some technical and economic indicators are also subject to several factors, such as the leaching rate, which is not only affected by the nature of the ore, but also by the technical level. Therefore, when selecting, determining and evaluating technical and economic indicators, we must seriously consider the main factors affecting the technical and economic indicators, and make appropriate conclusions through investigation and research, repeated comparisons.
The main factors affecting the economic indicators of heap leaching technology are:
First, the geological conditions of the deposit
There are ore bodies, occurrence status, depth of burial, total ore reserves and reserves levels, which have a great impact on the service life, scale and cost of the enterprise. There are many lessons about failure due to unclear geological conditions in the deposit, and a lot of investment is wasted.
Second, the nature of the ore
Including the grade, composition, hardness, grain size and water content of the ore, it is the main factor affecting the leaching rate and the amount of leaching agent, electricity consumption and water consumption, and is also the main influencing factor of wastewater discharge. It is also an important factor influencing the total investment.
Third, the technical level (including equipment level)
The first is that its reliability will determine the success or failure of the company, and its advanced nature will seriously affect the economic effects of the enterprise.
Fourth, the geographical and geographical conditions of the region
The natural conditions of the location of the enterprise, such as temperature, wind, terrain, rivers and rainfall, will affect the determination of process participation, and will have a great impact on the quantity and shape of the equipment, which will lead to changes in total investment and production costs.
V. Regional economic development level
For example, the economic status and transportation of the location of the enterprise have a significant impact on the total investment, production costs, and management costs.
6. National industrial policy and market conditions
This is an important factor affecting the overall economic performance of the company.
According to the relationship bewteen Paper Making Machine and coating machine, this series of paper coating machine is divided into online coating machine and offline coating machine. For different applications of coating paper, the coating mode is divided into single-side coating and double-side coating, each side can be coated one or more times. The coating machine is mainly uses air knife coater and blade coater, consisting of unwind system, coater, drying system, gloss calender system, regulating and finishing, reeling section and transmission system etc.
