Ore weight

The determination of the weight of the ore sample required for the test depends mainly on the following factors: the type and nature of the ore, the type of test, the scale and depth, the complexity of the ore dressing method and process, the specifications and capabilities of the test equipment, and the test run time. The weight of the ore sample shall be determined by the test research unit. The following is the general requirement for the weight of the ore sample. (1) Optional test and laboratory small process test The general requirements for the weight of the sample, see the table below. General requirements for the weight of the sample in the optional test and laboratory small process test

Test type	Ore type	Mineral processing method	Mineral sample weight, kg
Optional test	Magnetic iron ore	magnetic separation	100-200
	Hematite, siderite iron, non-ferrous metal ores, apatite, pyrite, chrome ore	Flotation, strong magnetic separation, roasting magnetic separation, reselection	200-300
	Multi-metal ore, manganese ore, silicon calcium phosphate rock, potassium ore, boron ore	Flotation and maglev joint selection	300～500
		Re-election	300-100
Test small process test	Magnetite	magnetic separation	200-400
	Hematite ore, siderite ore, non-ferrous metal ore, apatite, pyrite ore, chrome ore	Flotation, strong magnetic separation, roasting magnetic separation	500-1000
		Re-election	2000-3000
	Polymetallic ore, manganese ore, silicic calcium phosphate, potassium ore, boron ore	Flotation and maglev joint selection	1000-1500
		Re-election, floating weight joint selection	2500-4000
	Refractory oxidized ore mixed ore	Joint selection of smelting and smelting	4000 or more

(2) The laboratory expands the weight of the continuous test ore sample, usually 5000-10000kg. (3) The weight of the semi-industrial test and industrial test ore sample shall be determined according to the purpose of the test, the content of the test, the capability of the test equipment and the test time (the relevant test contents, test equipment capacity, test time, etc.) (4) The weight of the test ore sample containing precious metals and rare elements shall be calculated according to the content of the components and the required amount of the selected equipment in the test. (5) The use of new equipment, new processes, new technologies, new pharmaceutical agents and some For special tests, the amount of ore and sample weight to be added shall be requested by the experimental research unit.
