IS 1449 (2010): Methods of Sampling of Managanese Ores
5 SAMPLING FROM CONVEYORS BY STOPPED- BELT METHOD 5.1 When manganese ore is moved on conveyors, one of the most reliable methods of manual sampling is the stopped-belt method. Whenever, it is practicable to stop the conveyer belt periodically, a large quantity of ore known as unit sample may be drawn by stopping the belt. However, On arrival at the iron ore terminal at Saldanha, the ore is tipped from the rail trucks onto conveyor belts to be either stockpiled or direct-loaded. The conveyor belts run under the sampling plant and the ore is sampled periodically by means of an automated cross-belt sampler.

Sampling Procedures ScienceDirect
Abstract. Correct sampling and sample preparation practices are critical to obtaining meaningful analytical data in the gold industry for the accurate delineation of ore resources, metallurgical accounting, and the evaluation and control of mining and processing operations. The basic rule for correct sampling and sample processing is that allAfter establishing the quantity of ore onboard the barge, determine the total number of sub-samples required and divide the stow up into smaller sections. For each section, plan the sampling points so as to obtain the requisite number of sub-samples spread across the area concerned.

Abrasiveness of iron ores: Analysis of service-worn conveyor belts
Belt conveyors are currently one of the most commonly used technologies for transporting iron ore. Of the components of the conveyor system, the belt is the most expensive and susceptible to damage.

Experimental validation of a primary sampling system for iron ore
The reason for this discrepancy was investigated by thorough inspection of the complete sampling system, leading to the conclusion that the problem was not related to increment extraction, but rather due to dust accumulation on the conveyor belt during transportation of the primary increments to the first rotary sample divider.This problem Copper. The CNA³ design is particularly suited for conveyor belts carrying copper ore. The unit is designed to accommodate wide belts with variable loading and a wide range of particle sizes. With the entire unit below the belt, oversize material passes harmlessly over the analyzer.
