Developing a strategy to decontaminate a metal-polluted abandoned mining site involves several steps and the use of specific techniques and organisms. Here's a step-by-step guide:

1. **Site Assessment**: The first step is to assess the site to understand the extent of contamination, the types of metals present, and the physical and chemical characteristics of the site. This will help in determining the most suitable remediation strategy.

2. **Selection of Organisms**: Based on the assessment, select appropriate organisms that have the ability to tolerate and accumulate heavy metals. These could be certain types of bacteria, fungi, or plants (in a process known as phytoremediation). For instance, certain species of bacteria like Pseudomonas and Bacillus are known for their metal resistance and bioaccumulation capabilities.

3. **Inoculation**: Introduce these organisms into the site. This could be done through bioaugmentation (adding cultured organisms to the soil) or biostimulation (enhancing the growth and activity of existing organisms by adding nutrients or substrates).

4. **Monitoring**: Regularly monitor the site to check the progress of decontamination and the health of the introduced organisms. Adjust the strategy as needed based on the monitoring results.

5. **Post-Remediation Activities**: Once the desired level of decontamination is achieved, carry out post-remediation activities like site restoration and long-term monitoring to ensure the site remains safe.

In terms of microbial interactions, you would want to explore synergistic interactions where the presence of one organism enhances the metal-removal ability of another. For example, certain bacteria can enhance the growth of metal-accumulating plants by fixing nitrogen or solubilizing phosphorus. These interactions can make the decontamination process more efficient.

This strategy is based on the principle of bioremediation, which uses living organisms to clean up polluted environments. It's a sustainable and eco-friendly approach, but it requires careful planning and management to be successful.
