Metallurgic Processes | Boundless Chemistry
The term "refining" is used in a narrower context. Henry Cort's original puddling process only worked when the raw material was white cast iron, rather than the gray pig iron that was the usual raw material for finery forges. For the gray pig iron to be usable, a preliminary refining process was developed to remove the silicon.

Three palm oil fractionation processes which are in use: ... What is Refining? The crude oil obtained either from expellers or solvent extraction plant contains impurities, which must be removed to make the oil edible, more palatable and stable against rancidity upon storage. The process of removing these impurities is called refining.
Oil and Gas Drilling - The Process
6. 1. Directional drilling refers to turning the well to follow the path of the shale layer. 2. The Marcellus is just one shale layer from which drillers are attempting to extract oil and natural gas. 3. The fracturing of the shale in this part of the drilling process is where the term "fracking" originated. 4.

OIL REFINERY PROCESSES
Refining operations Petroleum refining processes and operations can be separated into five basic areas: • Fractionation (distillation) is the separation of crude oil in atmospheric and vacuum distillation towers into groups of hydrocarbon compounds of differing boiling-point ranges called "fractions" or "cuts."
CSB Investigation of BP Texas City Refinery Disaster ...
That year, the refinery experienced three major accidents that resulted in a total of three fatalities. One of these accidents was a major process-related fire. In late 2004, following these major accidents and other near misses, the Texas City leadership was attempting to improve the refinery's safety performance.
9 Step Process for Discovering, Mining & Refining Gold
Ore is first crushed and then undergoes various processes depending on the nature of associated minerals. Processing low-grade ore is relatively simple while higher grades require more extensive processing. Step #8 – Refining (off-site) Once basic processing is done, the ore is taken to a refinery where the remaining impurities are stripped out.
