Based on my analysis of this job listing, I'd like to offer the following tips and highlights:

Tips for a Successful Application:

1. In my experience, moulding your CV towards the specific job is critical. Highlight any experience you have in mineral processing engineering prominently.
2. Treat 'Relevant qualifications and experience' as a targeted call. Your CV should showcase qualifications in engineering and any specific modules or specialized studies tying back to 'mineral processing'.
3. Tailor your cover letter for this specific job. Discuss why you are interested in mineral processing and how your skills align with the company's mission.
4. In the context of employment opportunities in Zimbabwe, it's key to illustrate how your background or previous roles have prepared you for this position.
5. For vacancies in Zimbabwe like this, proofreading your CV is crucial. Incorrect contact details or spelling errors could cost you a job offer.

Areas Applicants Must Take Greater Note Of:

1. The email provided for application is specifically '[email protected]'. Always cross-verify to ensure you're sending your application to the correct email address.
2. The application process requests 'combined Cv and certificates'. Make sure to include all relevant certificates along with your CV.
3. There's no stated closing date for applications. What I have noticed overtime is, applying earlier tends to yield better results.
4. Do not be deterred even if you feel you might not meet all the job criteria. Highlight transferable skills and your zeal to learn on your application to make up for any potential shortcomings.
5. The duties and responsibilities aren't expressly stated - this is common with some jobs in Zimbabwe. Research the typical duties of a mineral processing engineer and align your application accordingly.

Ways to Stand Out in a Candidate Pool:

1. Relevant certifications related to mineral processing engineering will set you apart. If you lack on-the-job experience, academic prowess or related coursework can help.
2. Illustrating your adaptability and problem-solving skills with distinct examples from prior jobs – what I’ve encountered in the past is, these make you stand out in job vacancies in Zimbabwe.
3. Show enthusiasm for the industry and the specific company. Do some research on the industry and the company and mention this in your cover letter; it shows initiative and interest.

Important Aspects Novice Applicants Might Miss:

1. 'Relevant qualifications and experience' may seem vague but it is a valuable cue. This tells me they value both education and hands-on experience - make sure your application highlights both.
2. The fact that the job duties are listed as 'job related' tells me they are seeking someone who understands the standard duties of a mineral processing engineer - it would be beneficial to highlight your understanding of these in your application.
3. The application requires a 'combined Cv and certificates'. This might seem a minor instruction, but not adhering could reflect negatively on your attention to detail.

By adding these touches, your application will stand out not just among job vacancies in Zim, but also globally. Remember, the job search in Zimbabwe is increasingly competitive, so every opportunity counts.
