the mineral grains to be processed during the life of the plant. These characteristics are used as a basis for differentiation within a separation machine and process. The implementation of a mineral sands project presents challenges at each stage of execution due to a range of uncertainties that are unique to each project. These
A mineral project is first explored for and prospectors conduct early exploration activity to justify the decision to proceed with developing the project. Exploration efforts including geophysical surveys, surface sampling and drilling have all been conducted. The data gathered from exploration work is used to determine whether a company will continue to explore and develop a mineral resource. After a mineral resource is discovered, a qualified person and/or team of professionals will compile the exploration data into a technical report. All technical disclosures for mineral projects must follow National Instrument 43 101 Standards of Disclosure for Mineral Projects . The Canadian Securities Administrators developed the NI 43 101 rules to ensure that misleading or fraudulent information relating to mineral properties is not published and promoted to investors on the stock exchanges overseen by the Canadian Securities Authority. Canada is a leader in terms of how info...

After discovery and definition of an estimated tonnage of a mineral deposit, a company will want to proceed with project development. Engineering studies are typically the next phase of development and will require funding, much like any other exploration or development activity. Typically, a company will choose a mining engineering firm to conduct a Preliminary Economic Assessment , which is the first technical study that will assess the economic viability of a mineral project. After the PEA, the company will look to continue with exploration work to delineate more of its resource, evaluate any potential technical, economic, financial, social, political and environmental risks on its way to initiating further engineering studies. The Pre Feasibility and/or Feasibility studies completely answer the question of, is the project going to be profitable? If a project proves to be economically feasible, then the company will need to evaluate and finally locate sources of funding to t...
Planning occurs at all stages of the mineral exploration/development life cycle, however planning is a specific focus during the development stage. Planning in the development stage focuses on formal plans for project financing, permitting, construction, operation and finally, closure and reclamation.
Permitting requirements are a very important part of planning, as they will affect things like mine design, cost of development and site rehabilitation. Mining permits and most of the other authorizations for mineral exploration and mining activities fall under the jurisdiction of provincial / territorial governments. While the regulatory environment in Canada includes multiple steps, the system is generally reliable and stable. It is important for mining companies to have positive relationships with members of government in order to expedite and ensure efficient permitting for their projects.
The definition of sustainable development is development that meets the needs of the present without compromising the ability of the future. Mining, as conducted presently, is not a sustainable activity in that there is only a finite amount of resources on the planet. However, mining can be environmentally sustainable with proper remediation programs, which reset land to prior state to mining. Environmental assessments prior to mining consider physical impacts to the environment and mitigation measures. Additionally, mining companies can create sustainable economic growth for the communities in which they work by investing in things that benefit the wider communities of interest. Corporate social responsibility is at the heart of sustainable development and is something that miners have evolved to be more aware about. It is defined as a business approach contributing to sustainable development by delivering economic, social and environmental benefits for all stakeholders. Mining com...
The mining method must be considered when thinking about construction cost. A mining operation will either be classified as a surface mine or an underground mine. Underground mines present unique challenges for project developers compared to an open pit mine operation. Open pit mining is more cost effective, safe and less complex. Miners do not have to safeguard against loss of air or a cave in from directly above in an open pit. Operators are generally able to utilize larger equipment in their fleet in an open pit operation. Mining underground can become extremely complicated based on the vast infrastructure required. The cost of constructing an underground mine is inherently greater than that of an open pit mine. Some important infrastructure to consider is ore and personnel transport, ventilation, electricity and water. These are all extra considerations that have to be taken into account for an underground operation. On top of infrastructure, local geologies and rock...
Todays regulations in most countries ensure that all exploration and mine sites will be returned as near as possible to their previous conditions after mining is complete. This means that most equipment, buildings and facilities will be removed and any affected land reclaimed and restored. Some necessary monitoring equipment, buildings and facilities may remain. Planting and native species placements are used to restore disturbed ecosystems to what they were before the mine site was built. Reclamation occurs at every stage of the mineral exploration life cycle.
Ultimately, the mineral exploration and development process for any given project is something that often takes years to undergo. Junior explorers and miners assume the risk that comes with their business of mineral exploration and development. Junior mining or exploration companies utilize best practices to ensure a positive outcome at the conclusion of the mineral project development life cycle. For every company that has been able to develop their deposit into a producing mine, there are 100 that have not been as fortunate. However, for the people that do their research and decide to invest in the companies and teams that do get it right, there are usually very significant rewards.
Generally, simple mineral processing experiment need 15 working days, detailed mineral processing experiment need 30 working days. 1. Sampling and prepare the ore samples for experimental research. 2. Raw ore property test. 3. Preliminary exploration of experiment. 4. Concentrate and tailing analyze the recovery of valuable minerals.
Feasibility Study for Mineral Processing Plants Purpose and Tasks of Conducting A Feasibility Study Feasibility study is an evaluation of the potential of the proposed project on economy and technology. It is based on the project proposal approved by the direct supervisor, and is a very important task in the preliminary design.
Upgrades to mineral processing plant. After completing a prefeasibility study to determine the viability of making modifications to its processing plant to produce concentrates of copper, lead, and zinc, Ouray Silver Mines sought to complete the detailed engineering and construction associated with the new process arrangement.
