Estimation of mineral processing project (1)

Beneficiation plant design is to determine the total budget for the construction project total file concentrator completion of all infrastructure investment from planning to acceptance. The total budget for the project is to control the construction of infrastructure investment, to provide investment results evaluation, preparation of fixed asset investment plan, capital raising, construction bidding and implementation of major investment round contract basis, but also as the main basis for control construction design budget. After the approval of the general budget proposal, it shall not be broken at will. The preparation of the general budget plan must strictly implement the relevant national policies, policies and regulations.
The national design and budgetary documents preparation and management methods stipulate that the general budget estimates for the preliminary design phase of large and medium-sized construction projects, the construction drawing budget for the construction drawing design phase, and the revised general budget estimates for the technical design phase.
First, the budgetary composition
The capital construction budget estimates include the general estimate of the construction project, the comprehensive estimate of the individual project, the estimate of the unit project and other project and cost estimates.
The construction project refers to the feasibility study report and the overall design with approval, the independent accounting in the economy, and the basic construction unit with administrative organization in the form of independent organization. A construction project can consist of one or several individual projects (also called engineering projects). For example, the concentrating plant is a construction project, and its crushing, screening workshop, main plant, and concentrate processing workshop are single projects. A single project can be decomposed into unit projects such as construction engineering, equipment and installation engineering. A single project is a project that has an independent design document and can independently exert the production capacity or benefits specified by the design after completion. Unit engineering refers to a project that has an independent design and can independently organize construction. Each unit project can be further broken down.
The unit project budget is the original data and components of the preparation of the comprehensive project budget proposal, which is prepared by the professional designers first; then the budgetary experts prepare the comprehensive budget proposal; the general budget book is calculated by the budgetary professionals and the comprehensive budget estimates and other The project and cost estimate are compiled. Other engineering and cost estimates are other engineering and cost documents that are related to the construction, equipment and installation work, and are related to the entire construction project. They are included in the general estimate or the comprehensive budget estimate as separate items, including Construction unit management fees, land acquisition compensation fees, original building and structure migration compensation fees for construction sites, compensation for young crops and trees, survey and design fees, equipment and spare parts purchase fees, office and living equipment purchase fees, employees Training fees, temporary facilities fees, joint test fees, etc. [next]
The relationship and preparation procedures of the above project budget proposals are summarized below, as shown in the figure below.

Second, the ore dressing professional preparation unit project budget
The design of the mineral processing professional is nearing completion of the preliminary design of the concentrator. The last task is to prepare the budgetary calculation for the mineral processing, which is the cost of each single project such as crushing, sieving, main plant, concentrate processing and other production workshops and tests and laboratories. The unit project budget estimate is mainly “Equipment and Installation Engineering Estimation Table”, which includes the estimated value of the three parts of the beneficiation process equipment, metal structural parts and process piping. [next]
1. Equipment estimated value Equipment estimated value = equipment original price + equipment transportation miscellaneous charge + equipment installation overhead fee The original equipment price is the standard equipment in the equipment list, according to the national unified price (including the floating factors considered); the non-standard equipment value needs to be based on relevant information Estimate.
Equipment transportation and miscellaneous charges = equipment original price * transportation miscellaneous rate equipment installation overhead fee = equipment original price * installation indirect rate The regional transportation and miscellaneous rates are shown in the following table:

The installation overhead rate is shown in the following table:

2. Calculation of estimated value of metal structure parts of metal structure Estimated value of metal structure parts = weight of metal structure parts * unit weight price The weight of metal structure parts can be determined according to preliminary design drawings or actual expansion indicators, and the expansion index of metal structure parts is shown in the following table. The unit weight price depends on the processing and material.
