While commodities generally follow those covered in the USGS Mineral Commodity Summaries available online at <http://minerals.usgs.gov/minerals/pubs/mcs/>, in some cases descriptors are added to give information about the raw material, or process used. In some cases multiple commodities are processed at a site; all commodities pertaining to a site are listed in this field and there is no standard set of possible combinations though some combinations are more likely than others to occur.
| Value | Definition |
|---|---|
| - | Mining method is not known or is not applicable because the operation is a processing plant rather than a mine |
| S | The mine is an open-pit or other surface mine |
| S, U | The mine is an open-pit or other surface mine and also has an underground component |
| U | The operation is a an underground mine |
| U, S | The mine is an underground mine with surface operations as well |
No standard set of company names exists
| Value | Definition |
|---|---|
| - | The status of the operation is not known |
| active | The operation was producing in 2004 |
| closed | The operation was closed in 2004 |
Capacity is numeric however in some records descriptors such as material being measured were added; some records may have capacities for different commodities. Capacities in different records can not be directly compared because units of measurement vary between records; the units are given in a different field in the record.
| Value | Definition |
|---|---|
| 42 gallon barrels / day | The plant capacity is measured by number of 42 gallon barrels that can be produced per day |
| 42 gallon barrels / yr | The plant capacity is measured by number of 42 gallon barrels that can be produced per year |
| carats / yr | The plant capacity is measured in number of carats of the commodity that can be produced per year |
| cubic meters/yr | The plant capacity is measured in number of cubic meters of the commodity that can be produced per year |
| kg / yr | The plant capacity is measured in number of kilograms of the commodity that can be produced per year |
| million 42 gallon barrels / yr | The plant capacity is measured in millions of 42 gallon barrels that can be produced per year |
| million cubic meters | The plant capacity is measured in million cubic meters but it is not known if it is per year or per day |
| million cubic meters / yr | The plant capacity is measured by the millions of cubic meters of the commodity that can be produced per year |
| t / yr | The plant capacity is measured in tons per year -- it is not known whether these are short tons or metric tons |
| t / yr, kg / yr | The plant capacity for the first commodity listed in the commodity field is measured in tons per year -- it is not known whether these are short tons or metric tons, and the plant capacity for the second commodity is measured in kilograms that can be produced per year |
| thousand 42 gallon barrels / day | The plant capacity is measured in thousands of barrels that can be produced per day that each hold 42 gallons |
| thousand 42 gallon barrels / yr | The plant capacity is measured in thousands of barrels that can be produced per year that each hold 42 gallons |

The purpose of this data set is to present information about the mineral facilities of Africa and the Mineral East, including their location, ownership or operating company, operating status, and capacity. This data set reflects the mineral operations pertinent to commodities discussed in the International Minerals Yearbook chapters of the USGS.

Data sources used in this process:
Data sources used in this process:
No gurarantee is made as to the accuracy of the attributes. Attributes values represent best-available data from research of sources such as statistical publications of individual countries, annual reports and press releases of operating companies, and trade journals. Coordinates were added by researching the company name and general location; in some cases coordinates may be that of the nearest town or province centroid. Due to the sensitivity of some energy commodity data, the quality of these data should be evaluated on a country-by-country basis.
The coordinates of the operations were obtained at a world scale. In many cases the coordinates are those of nearby cities or province centroids, especially where the site name is that of a city or province.
The data were gathered in support of the USGS Minerals Yearbook (Volume III. -- Area Reports: International). An attempt was made to include operations known to be or have been economically significant and therefore included in the Yearbook tables, if not directly mentioned then these operations in some way were ones for which production numbers were calculated to create the Yearbook tables. This downloadable data set is missing 141 operations for which coordinates could not be found; however the USGS Open File Report 2006-1135 (the larger work from which this data set is derived) lists these operations without their coordinates.
No test for logical consistency was performed on this data set. It should be noted that values for the field describing plant capacities are in various units of measure; another field records the unit of measure.
Are there legal restrictions on access or use of the data?
- Access_Constraints: None
- Use_Constraints:
- None, however the responsibility of determining fitness for any particular use is that of the user of these data.
