A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished goods, energy, or intermediate materials that are feedstock for future finished products. As feedstock, the term connotes these materials are bottleneck assets and are required to produce other products.
Materials science is the study of materials, their properties and their applications. Raw materials can be processed in different ways to influence their properties, by purification, shaping or the introduction of other materials. New materials can be produced from raw materials by synthesis.
The means of production includes two broad categories of objects: instruments of labor (tools, factories, infrastructure, etc.) and subjects of labor (natural resources and raw materials). People operate on the subjects of labor using the instruments of labor to create a product; or stated another way, labor acting on the means of production ...
Elizabeth Kolbert, "Needful Things: The raw materials for the world we've built come at a cost" (largely based on Ed Conway, Material World: The Six Raw Materials That Shape Modern Civilization, Knopf, 2023; Vince Beiser, The World in a Grain; and Chip Colwell, So Much Stuff: How Humans Discovered Tools, Invented Meaning, and Made More of ...
A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill. The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the ...
In the Marxist theory of historical materialism, a mode of production (German: Produktionsweise, "the way of producing") is a specific combination of the: . Productive forces: these include human labour power and means of production (tools, machinery, factory buildings, infrastructure, technical knowledge, raw materials, plants, animals, exploitable land).
