Factorio is a construction and management simulation game focused on resource-gathering with real-time strategy and survival elements. The player advances by locating and harvesting resources to craft various tools and machines, which in turn create more advanced materials that allow for the progression to more sophisticated technologies and ...
The player (a "Pioneer") is dropped onto an alien planet with a handful of tools and must exploit the planet's natural resources to construct increasingly complex factories. The initial goal is to construct a space elevator , through which the Pioneer begins supplying the megacorp the player works for (FICSIT Inc.) with increasingly numerous ...
In its most basic form the ores were piled in a mound and ignited. The semi-pure sulfur flowed down and the solidified mass was collected at a lower level. It was the only industrial method of recovering sulfur from elemental deposits until replaced by the Frasch process. [1] Most of the world's sulfur was obtained this way until the late 19th ...
The vast majority of the 64,000,000 tonnes of sulfur produced worldwide in 2005 was byproduct sulfur from refineries and other hydrocarbon processing plants. [3] [4] [5] Sulfur is used for manufacturing sulfuric acid, medicine, cosmetics, fertilizers and rubber products. Elemental sulfur is used as fertilizer and pesticide.
The wet sulfuric acid process (WSA process) is a gas desulfurization process. After Danish company Haldor Topsoe introduced this technology in 1987, it has been recognized as a process for recovering sulfur from various process gases in the form of commercial quality sulfuric acid (H 2 SO 4) with the simultaneous production of high-pressure steam.

What set in motion the large-scale exploitation of Sicilian sulfur was the discovery of the Le Blanc method (1787) for the industrial-scale manufacture of soda ash. Sulfur, also a key ingredient in the production of gunpowder, then assumed a strategic importance equal to that held in the modern era by uranium.
A die is a specialized machine tool used in manufacturing industries to cut and/or form material to a desired shape or profile. Stamping dies are used with a press, [1] as opposed to drawing dies (used in the manufacture of wire) and casting dies (used in molding) which are not. Like molds, dies are generally customized to the item they are ...
