A console is a command line interface where the personal computer game's settings and variables can be edited while the game is running. Consoles also usually display a log of warnings, errors, and other messages produced during the program's execution. Typically it can be toggled on or off and appears over the normal game view.
On MS-DOS, the command is available in versions 2 and later. [10] DR DOS 6.0 [11] and Datalight ROM-DOS [12] include an implementation of the find command. The FreeDOS version was developed by Jim Hall and is licensed under the GPL. [13] The Unix command find performs an entirely different function, analogous to forfiles on Windows.
Command-line completion allows the user to type the first few characters of a command, program, or filename, and press a completion key (normally Tab ↹) to fill in the rest of the item. The user then presses Return or ↵ Enter to run the command or open the file.
A command prompt (or just prompt) is a sequence of (one or more) characters used in a command-line interface to indicate readiness to accept commands. It literally prompts the user to take action. A prompt usually ends with one of the characters $ , % , # , [ 18 ] [ 19 ] : , > or - [ 20 ] and often includes other information, such as the path ...
In the sixteenth century, heap leaching became commonly used to extract copper and saltpeter from organic matter. [4] Primarily used in Germany and Spain, pyrite would be brought to the surface and left out in the open. [4] [3] The pyrite would be set outside for months at a time, where rain and air exposure would lead to chemical weathering. [4]
Copper is precipitated as its sulfide as a means to purify nickel leachates. Cementation is the conversion of the metal ion to the metal by a redox reaction. A typical application involves addition of scrap iron to a solution of copper ions. Iron dissolves and copper metal is deposited. Solvent Extraction; Ion exchange; Gas reduction.
The possibility of using microorganisms in biomining applications was realized after the 1951 paper by Kenneth Temple and Arthur Colmer. [9] In the paper the authors presented evidence that the bacteria Acidithiobacillus ferrooxidans (basonym Thiobacillus ferrooxidans) is an iron oxidizer that thrive in iron, copper and magnesium-rich environments.

Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct ...
