It can be expensive and harmful to the environment.
yes it can be harmful yet it can cause dormant toxins in the ore to become active.
Not to mention that the more you mine the ore the actual gangue becomes higher than the actual value of the ore itself, therefore ridding it of the classification "ore"
(gangue: the commercially valueless material in which ore is found.)

What else can I help you with?
Why do mining lead to waste heaps on the surface?
Mining leads to waste heaps on the surface because during the mining process, large amounts of unwanted or low-grade material are excavated along with the desired ore. This waste material, known as overburden, must be stored on the surface since it is not economically feasible to transport it elsewhere. Additionally, waste heaps can result from the processing of the mined ore, where tailings containing unwanted materials are separated and stored above ground.
Why should the sulfur dioxide be removed from the waste gases?
Sulfur dioxide should be removed from waste gases because it is a major air pollutant that can contribute to acid rain, respiratory problems, and environmental damage. By removing sulfur dioxide, we can reduce these negative effects and improve air quality.
Waste rock that must be removed before a mineral can be used?
The waste rock that must be removed before a mineral can be used is known as ore. The process of removing waste rock to extract valuable minerals is called mining. This waste rock is separated from the ore during the mining process.
Why is waste coal good for the environment?

The type of waste in most landfills?
The type of waste found in most landfills includes household garbage, construction debris, electronic waste, and organic material like food waste and yard trimmings. These materials can take a long time to break down and may generate harmful gases and leachate if not managed properly.
What problems can result from removing waste material from ore?
Removing waste material from ore can lead to environmental issues such as soil and water contamination, habitat destruction, and disruption of ecosystems due to the disposal of tailings. Additionally, the process can cause air pollution from dust generation and the release of harmful chemicals. Finally, there may be safety concerns for workers due to exposure to hazardous materials during the removal process.
What causes material usage variance?
Material usage variance can be caused due to waste. Quality issues, such as defects, can result in material usage variance.
What can waste material be made into?
Waste material can be made, into what ever you want it to be!
Is feces organic?

What were one of the most difficult new problems generated by the rise of cities and the urban American life-style?
Disposing of large quantities of waste material.
How can government overcome sewage problems?
The solution to sewage problems is to install a more efficient system that can handle larger volumes of raw material. Improving the efficiency of the system so that it can process higher volumes of waste.
Which body system is responsible for removing waste from the bloodstream?
