Problems solved by technology

Judging from the published literature at home and abroad, due to large errors in the detection of raw ore grades in the mining production process, it is impossible to accurately know the average grade of a certain pile of ore. Therefore, the existing research on ore blending only stays in mining production. There is no public report on the ore blending method for the whole production link from ore blending in the mining field to ore blending in the concentrate bin with the goal of selecting the grade of phosphate ore

Embodiment Construction

[0022] A method for mixing phosphate rock into raw ore, comprising the following steps:

[0023] 1) Data collection;

[0024] 2) Determine the ore blending target of each production link, so that in the process of formulating ore blending, the raw ore grade that each production link should reach;

[0025] 3) Build a model;

[0026] 4) Output raw ore blending plan;

[0027] The model described is:

[0028] Σ i = 1 N x i = max ( H in = null ) , i=1...N. Objective function (1)

[0029] Σ i = 1 N x i ( H in = ...

Abstract

The invention relates to an ore-matching method of selecting phosphorus ore to raw ore. The method comprises the following steps: 1) data are collected; 2) an ore-matching target of each production ring is ensured to ensure that in the ore-matching process, each production process achieves the raw ore grade; 3) a model is built; and 4) an ore-matching scheme of the raw ore is output. An effective ore-matching method is provided. Due to the adoption of three grades of ore-matching modules, namely, ore-matching of the raw ore in a collecting field, ore-matching of an ore heap in a selected dressing plant heap and ore-matching of a concentrate store, the effect of errors to average grade calculation of the ore is gradually corrected and detected, and meanwhile haul distances are calculated, transportation cost is greatly reduced, and the stable ore grade has important significance in stabling production technology of the ore dressing plant, reducing energy consumption and improving production efficiency.

Description

technical field [0001] The invention belongs to the technical field of beneficiation production, and in particular relates to an ore blending method for phosphate rock to be selected as raw ore. Background technique [0002] The mass distribution of ore in any mine is always uneven within the scope of the whole deposit. In order to ensure the normal production of the concentrator and obtain good technical and economic indicators, the quality indicators of the selected ore must be balanced and stable. To this end, the ore needs to be blended and mixed. The ore blending is usually carried out in the mining field, on the stockyard before coarse crushing or in the concentrate bin; the mixing is carried out in the process of crushing, screening and transportation. Judging from the published literature at home and abroad, due to large errors in the detection of raw ore grades in the mining production process, it is impossible to accurately know the average grade of a certain pil...
