The sugar crystals are dissolved in water and poured through a series of filters until the liquid is clear. The syrup is heated so the liquid evaporates leaving crystals again. The crystals are spun in a centrifuge

This entry includes establishments primarily engaged in refining purchased raw cane sugar and sugar syrup. Sugar cane is cut and milled into raw cane sugar, then shipped in that form to refiners to be processed into syrup, granulated sugar, powdered sugar
Precipitation helps to separate impurities from the sugar cane juice by causing them to form clumps or settle at the bottom, allowing the pure sucrose to remain in solution. This technique is commonly used in the sugar refining process to purify the sugar cane juice before further processing.
SIC 2062 covers Cane Sugar Refining
To produce 1 ton of blackstrap molasses, approximately 10 to 12 tons of sugarcane are required. This is because blackstrap molasses is a byproduct of sugar extraction, and a significant amount of sugar is extracted from the cane during the refining process. The exact amount can vary based on factors such as the sugar content of the cane and the efficiency of the extraction process.

No, white sugar is not made from cow bones. White sugar is typically made from sugar cane or sugar beets, which are plants. The process of making sugar involves extracting the natural sugars from these plants and refining them into the white sugar crystals that we commonly use.
The process of refining raw materials to table sugar typically involves washing, crushing, and extracting juice from sugar cane or sugar beets. The juice is then clarified, filtered, and heated to evaporate the water and concentrate the sugar. The concentrated syrup is further purified through processes like crystallization, centrifugation, and drying to produce granulated sugar.
The basic process is to mash up the cane to extract the juice, then evaporate the liquid portion to leave behind the sugar. As you might imagine, there are intermediate steps of refining to get the pure white substance. Minimal refinement (such as just filtering to get out the shreds of cane) give brown sugar. Mild refinement gives "blonde" sugar (sometimes called "turbinado" sugar).

Making sugar is a process of refining the juice from sugar cane, then adding back the various bits necessary (the molasses) (unless making white sugar) to achieve the various degrees of brown sugar. So muscovado is a combination of white sugar and molasses. However some companies only partially refine the juice from the sugar cane, which avoids them having to add the molasses back to the sugar.
