A cannabis concentrate results from a process that reduces the cannabis flower to a malleable mass. Depending on the process, cannabis is delivered as oil, butter, wax, or crystal. Each by-product has its street name, and those labels change and multiply. You might be looking at budder, cannabis oil, dabs, black glass, butane honey oil, ear …

This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis. Following mining, transporting, and crushing to a consistent gravel or golf ball-size, the crushed ore is further processed at a mill ...

This process may be as simple as washing black sands in a gold pan. Mineral concentrates may go through several stages of cleaning before a final concentrate is produced. Equipment used for cleaning is often the same as that used for roughing. A sluice used for cleaning black sand concentrates is one example of a rougher used as a …
