Production of Manufactured Sand | SpringerLink
Parent rock: the mined raw materials are transported to the raw material form with rainproof facilities and fed to the vibrating feeder. (2) Soil removal: the soil in raw materials is removed through the vibrating feeder to prevent unclean raw materials from entering the production line. (3)
The raw-materials challenge: How the metals and mining …
The required pace of transition means that the availability of certain raw materials will need to be scaled up within a relatively short time scale—and, in certain cases, at volumes ten times or more than the current market size—to prevent shortages and keep new-technology costs competitive (see sidebar "Rare-earth metals").
Detailed Classification of B2B Goods
Processed Materials – These are products created through the processing of basic raw materials. Thus, in contrast to raw materials, they have already been worked on and are processed somehow. Sometimes, the processing refines original raw materials while in other cases the process combines different raw materials to create something new.

Naive Bayes Classifier Tutorial: with Python Scikit-learn
It performs well in case of discrete response variable compared to the continuous variable. It can be used with multiple class prediction problems. It also performs well in the case of text analytics problems. When the assumption of independence holds, a Naive Bayes classifier performs better compared to other models like logistic regression.
