Some GM(1,1) models are established by gray system theory. They are used to forecast the intensities of the demand on energy minerals for primary,secondary and tertiary industries and urban and rural residents and the changes of population development and industrial frame in Shandong Province.
In consideration of the circular economy, mining industryalso need to be "feed parents" which depend on a series of modification onmanagement system and the industry policy, at first, we should define the miningindustry definitely, make its independent, foundational industrial position in thestrategy of the national economy , and adjust a high tax and fee.
This technology when qpplied in industrial production can achieve a recovery of filtering operation of up to 99% and a dewatering rate of filter cake of ≥70%,which has provided a realistic example of realizing the industrialization of the filtration of low concentration ultra fine bleached clay minerals.
According to the present situation of coal industrial development ,we have analysed some safety problem that arouses from methane gas, introduced the mature and potential application of vacuum equipment to this profession, and put forward that the application of vavuum pump to the coal industrial, can meet safety demand, accord with the basic national policy of the circulating economy, energy saving economy and continuable development.
However, whatever method is used, real industrial applications need to establish well-defined and widely accepted protocols for validating the models and defining their robustness, prediction power and applicability domain.
New Synthetic Method for Industrial Manufacture of Glutaric Dialdehyde
This method is reproducible and simple and thus can be readily scaled up for industrial production.
The solid-state chemical method has the advantages of low cost, low pollution, and high yield, therefore it appears to be a promising method in the industrial manufacture of nanometer MgO.
