Tantalum minerals contain 12 to 84 percent tantalum pentoxide; however, tantalum ores are low grade and contain only 0.01 to 1 percent tantalum pentoxide, which is equivalent to 0.1 to 10 kilograms per metric ton. As a result, to produce concentrates of tantalum, tantalite ore must be separated from other minerals in the ore.
In a comminution circuit, there are four variables that influence the utilization of the power available to comminute the ore. Feed size. Product size. Resistance to breakage. Feed rate. Beyond these four are other factors, such as: Breakage patterns. Pulp density. Moisture content in the ore.

Tantalum ore grades vary but are generally somewhere between 100 and 400ppm Ta 2 O 5. The process begins with blasting to free the ore, which is then crushed and the tantalum concentrated by gravity separation. Typically, the ore is concentrated to around 5% Ta 2 O 5 at or near the mine site.
In 2021, estimated U.S. imports for consumption increased by 6%. Most of the tantalum imported was in the form of metal and powder (45%), followed by ores and concentrates (30%), and waste and scrap (24%). Waste and scrap imports saw the most significant variation by declining 37% from that in 2020. Estimated U.S. exports increased by 39% …

cases, tantalum minerals are separated from the concentrate using a dry method. Most of the tantalum, how ever, is smelted along with tin ore concentrate and then enriched in a slag.4 Depending on the ore types, the tantalum yield may vary between 40 and 85%. Slags with a high tantalum content of 8% Tap5 are digested in the same

Abstract. On-going technological developments, especially in the field of microelectronics and communication have reflected in concomitant increase in the demand for strategic metals such as tantalum (Ta) and niobium (Nb). The extraction of these two metals from ore deposits and secondary resources is based on the generic extractive ...
