The chromite mining process depends on the characteristics of the ore deposit. These characteristics tell us whether the deposit is high grade or low grade, along with other things. Surface mining is more ideal than underground mining, because it is usually less expensive, but it isn’t always possible. Beneficiation (crushing and separating ore into valuable substances or waste by any of a variety of techniques) for chromite also depends on the characteristics of the ore deposit and on the mining procedure used previously used. Take, for example, an operation extracting only high-grade ore might require only hand sorting and screening. Beneficiation is necessary when chromite mineral is mixed with other minerals because of geologic conditions or when mechanized mining methods are nonselective.

While scissors are usually made of steel, some scissors used for special purposes are made from other metal fusions. Scissors used to cut cordite (an explosive substance resembling twine) can not be allowed to produce sparks while cutting the substance. Scissors used to cut magnetic tape must not interfere with magnetism of the tape.
