Answer:
C) marketing and selling products that use ore materials.
Step-by-step explanation:
Mining can be defined as the process of extracting mineral resources from the Earth's surface such as seem, placer, ore-body, vein etc. Some examples of minerals that can be mined are gravel, gold, chalk, petroleum, limestone, coal, potash, rock salt etc.
The various techniques used for mining includes the following; placer mining, sluicing, hydraulic mining and hard rock mining.
The mining-resource cycle determines the use of ore materials. Some of the steps of the mining-resource cycle includes the following;
1. Exploring and extracting ores: this is the first step of the mining process and it typically involves having a good understanding of the characteristics of the land mass and its potential mineral deposits through the use of geophysical measuring instruments, sampling, geochemical analysis etc.
2. Refining ores and creating products from ore materials: at this stage, the impure mineral deposits (ore) undergoes a purification process so as to remove all impurities and making them ready for use in manufacturing other products.
3. Recycling and disposing of wastes from the steps and the products: this involves making the land free of hazardous materials and contaminants in order to make it useful again.
Hence, the step which is not part of the mining-resource cycle is marketing and selling products that use ore materials.
