In the concrete industry, people have tried to use fibe [22], biochar [23], and some solid waste [24] to reduce the use of cement, and this method has achieved excellent results. Using phosphorus tailings as cement mixture to replace part of cement, which could absorb phosphorus tailings in large quantities and has good economic value. S.
Although the "cement vein" was never found, many prospectors did find gold resulting in the mining camps of Dogtown, Mammoth City, Lundy Canyon, Bodie, and many others. It is also possible that the cement mine was rediscovered at some point during the last 150 years, without the finders knowing it. Lost Cement Mine Historical Marker.
The process of making cement begins with mining, where raw materials are extracted from quarries. Huge machines called excavators dig the limestone out of the …
At the site, the whole process including cement mining, grinding and delivery has been digitalized and intelligently controlled.

In the first scenario, it was assumed that all power (excluding heat energy) required for clinker/cement production, mining, mineral processing, smelting, mine backfill mixing, and transportation was sourced from diesel. Notably, according to the U.S. Energy Information Administration, the energy density of diesel is about 12.51 kWh/kg.
The use of cementation process and replacement of cement with mine tailings in the manufacture of concrete is one of the practical approaches to the management of mine tailings.

Development of the continuous silo concept started with the introduction of raw material preblending systems in the cement process out of the need to reduce power consumption for cement raw meal homogenization. The increasing efficiency of such blending systems went along with a gradual reduction of the size of blending silos. Process Concept
Cement mill-3 of 110 TPH at 2900-3000 cm 2 /gram Blaine. The ground cement is stored in five silos for final dispatch. A dynamic separator was installed in place of the old separator in cement mill-1 to improve the grinding capacity as well as the cement strength at lower fineness to meet the requirement of international standard for strength.
In the design of a large cement plant, the raw fuel, especially limestone, is equipped with a pre-homogenization yard, but because limestone has been consciously matched in the mining process, and the daily amount is particularly large, the role of limestone pre-homogenization yard for storage is higher than the homogenization effect. …
