Mineral ores,coal
A rich deposit of a valuable mineral is called an ore deposit. These deposits contain high concentrations of the mineral sought after by mining companies. The extraction and processing of these ores are critical for obtaining the valuable mineral.
When people remove minerals from the Earth, it is called mining. This process involves extracting valuable resources such as metals, coal, and gemstones from the ground. Mining can take various forms, including surface mining and underground mining, depending on the location and type of mineral being extracted. It often has significant environmental impacts, necessitating regulations and sustainable practices.
Smelting is a classic method of separating metals from (refining) ore. It's been around a long time. Chemical refining works well for certain metals. It came along more recently as chemistry evolved. Electro-refining depends on (what a surprise) electricity, and it is in common use nowadays.
Opal is a valuable mineral that starts with the letter "O." It is known for its unique play of colors and is often used in jewelry.
Negligible mineral resources are those that have little to no economic value due to factors such as low abundance, poor quality, or high extraction costs. These resources are typically not worth extracting or exploiting compared to other more valuable mineral resources.
In the context of mineral deposits, "rich" means that the area or deposit contains a high concentration or abundance of valuable minerals such as gold, silver, copper, or other economically significant minerals. It indicates that the location has a high potential for mining or extracting valuable resources.
In the field of extractive metallurgy, mineral processing, also known as mineral dressing or ore dressing, is the process of separating commercially valuable minerals from their ores.
The process of extracting a useful substance from an ore typically involves crushing the ore to release the desired mineral, then separating the mineral from the gangue (unwanted material) using physical or chemical methods such as gravity separation, flotation, or leaching. Finally, the extracted mineral is further refined to obtain the desired substance in its pure form.
Gold is a valuable mineral
Ohio's most important resources are fertile soils, and valuable mineral deposits such as coal, oil, natural gas, and rock salts.

Some of California's most valuable industrial mineral resources include sand and gravel, cement, and diatomite. These minerals are used in various industries such as construction, agriculture, and manufacturing. California is also a leading producer of rare earth elements used in high-tech industries.
