It's more about their impact on the environment and the mining process itself:
1. Boron: While boron is not typically a major concern in manganese mining, its presence in the soil can affect the extraction process. High boron levels can interfere with the efficiency of certain extraction methods.
2. Phosphorus: Phosphorus can be a contaminant in mining operations, especially if the mining site is near agricultural areas. It can affect the quality of the extracted manganese and the surrounding environment.
3. Silica: Silica is often present in the ore and can affect the processing of manganese. High silica content can increase the cost and complexity of extraction, as it requires additional steps to separate the silica from the manganese.
Hope this helps
